mysqld Ver 10.5.4-MariaDB-log for Win64 on AMD64 (mariadb.org binary distribution) Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Starts the MariaDB database server. Usage: mysqld [OPTIONS] NT and Win32 specific options: --install Install the default service (NT). --install-manual Install the default service started manually (NT). --install service_name Install an optional service (NT). --install-manual service_name Install an optional service started manually (NT). --remove Remove the default service from the service list (NT). --remove service_name Remove the service_name from the service list (NT). --enable-named-pipe Only to be used for the default server (NT). --standalone Dummy option to start as a standalone server (NT). Default options are read from the following files in the given order: C:\Windows\my.ini C:\Windows\my.cnf C:\my.ini C:\my.cnf d:\Programme\MySQL\my.ini d:\Programme\MySQL\my.cnf d:\Programme\MySQL\data\my.ini d:\Programme\MySQL\data\my.cnf The following groups are read: mysqld server mysqld-10.5 mariadb mariadb-10.5 mariadbd mariadbd-10.5 client-server The following options may be given as the first argument: --print-defaults Print the program argument list and exit. --no-defaults Don't read default options from any option file. The following specify which files/extra groups are read (specified before remaining options): --defaults-file=# Only read default options from the given file #. --defaults-extra-file=# Read this file after the global files are read. --defaults-group-suffix=# Additionally read default groups with # appended as a suffix. --allow-suspicious-udfs Allows use of UDFs consisting of only one symbol xxx() without corresponding xxx_init() or xxx_deinit(). That also means that one can load any function from any library, for example exit() from libc.so --alter-algorithm[=name] Specify the alter table algorithm. One of: DEFAULT, COPY, INPLACE, NOCOPY, INSTANT --analyze-sample-percentage=# Percentage of rows from the table ANALYZE TABLE will sample to collect table statistics. Set to 0 to let MariaDB decide what percentage of rows to sample. -a, --ansi Use ANSI SQL syntax instead of MySQL syntax. This mode will also set transaction isolation level 'serializable'. --aria-block-size=# Block size to be used for Aria index pages. --aria-checkpoint-interval=# Interval between tries to do an automatic checkpoints. In seconds; 0 means 'no automatic checkpoints' which makes sense only for testing. --aria-checkpoint-log-activity=# Number of bytes that the transaction log has to grow between checkpoints before a new checkpoint is written to the log. --aria-encrypt-tables Encrypt tables (only for tables with ROW_FORMAT=PAGE (default) and not FIXED/DYNAMIC) --aria-force-start-after-recovery-failures=# Number of consecutive log recovery failures after which logs will be automatically deleted to cure the problem; 0 (the default) disables the feature. --aria-group-commit=name Specifies Aria group commit mode. Possible values are "none" (no group commit), "hard" (with waiting to actual commit), "soft" (no wait for commit (DANGEROUS!!!)) --aria-group-commit-interval=# Interval between commits in microseconds (1/1000000 sec). 0 stands for no waiting for other threads to come and do a commit in "hard" mode and no sync()/commit at all in "soft" mode. Option has only an effect if aria_group_commit is used --aria-log-dir-path=name Path to the directory where to store transactional log --aria-log-file-size=# Limit for transaction log size --aria-log-purge-type=name Specifies how Aria transactional log will be purged. One of: immediate, external, at_flush --aria-max-sort-file-size=# Don't use the fast sort index method to created index if the temporary file would get bigger than this. --aria-page-checksum Maintain page checksums (can be overridden per table with PAGE_CHECKSUM clause in CREATE TABLE) (Defaults to on; use --skip-aria-page-checksum to disable.) --aria-pagecache-age-threshold=# This characterizes the number of hits a hot block has to be untouched until it is considered aged enough to be downgraded to a warm block. This specifies the percentage ratio of that number of hits to the total number of blocks in the page cache. --aria-pagecache-buffer-size=# The size of the buffer used for index blocks for Aria tables. Increase this to get better index handling (for all reads and multiple writes) to as much as you can afford. --aria-pagecache-division-limit=# The minimum percentage of warm blocks in key cache --aria-pagecache-file-hash-size=# Number of hash buckets for open and changed files. If you have a lot of Aria files open you should increase this for faster flush of changes. A good value is probably 1/10 of number of possible open Aria files. --aria-recover-options[=name] Specifies how corrupted tables should be automatically repaired. Any combination of: NORMAL, BACKUP, FORCE, QUICK, OFF --aria-repair-threads=# Number of threads to use when repairing Aria tables. The value of 1 disables parallel repair. --aria-sort-buffer-size=# The buffer that is allocated when sorting the index when doing a REPAIR or when creating indexes with CREATE INDEX or ALTER TABLE. --aria-stats-method=name Specifies how Aria index statistics collection code should treat NULLs. One of: nulls_unequal, nulls_equal, nulls_ignored --aria-sync-log-dir=name Controls syncing directory after log file growth and new file creation. One of: NEVER, NEWFILE, ALWAYS --auto-increment-increment[=#] Auto-increment columns are incremented by this --auto-increment-offset[=#] Offset added to Auto-increment columns. Used when auto-increment-increment != 1 --autocommit Set default value for autocommit (0 or 1) (Defaults to on; use --skip-autocommit to disable.) --automatic-sp-privileges Creating and dropping stored procedures alters ACLs (Defaults to on; use --skip-automatic-sp-privileges to disable.) --back-log=# The number of outstanding connection requests MariaDB can have. This comes into play when the main MariaDB thread gets very many connection requests in a very short time (Automatically configured unless set explicitly) -b, --basedir=name Path to installation directory. All paths are usually resolved relative to this --big-tables Old variable, which if set to 1, allows large result sets by saving all temporary sets to disk, avoiding 'table full' errors. No longer needed, as the server now handles this automatically. --bind-address=name IP address to bind to. --binlog-annotate-row-events Tells the master to annotate RBR events with the statement that caused these events (Defaults to on; use --skip-binlog-annotate-row-events to disable.) --binlog-cache-size=# The size of the transactional cache for updates to transactional engines for the binary log. If you often use transactions containing many statements, you can increase this to get more performance --binlog-checksum=name Type of BINLOG_CHECKSUM_ALG. Include checksum for log events in the binary log. One of: NONE, CRC32 --binlog-commit-wait-count=# If non-zero, binlog write will wait at most binlog_commit_wait_usec microseconds for at least this many commits to queue up for group commit to the binlog. This can reduce I/O on the binlog and provide increased opportunity for parallel apply on the slave, but too high a value will decrease commit throughput. --binlog-commit-wait-usec=# Maximum time, in microseconds, to wait for more commits to queue up for binlog group commit. Only takes effect if the value of binlog_commit_wait_count is non-zero. --binlog-direct-non-transactional-updates Causes updates to non-transactional engines using statement format to be written directly to binary log. Before using this option make sure that there are no dependencies between transactional and non-transactional tables such as in the statement INSERT INTO t_myisam SELECT * FROM t_innodb; otherwise, slaves may diverge from the master. --binlog-do-db=name Tells the master it should log updates for the specified database, and exclude all others not explicitly mentioned. --binlog-file-cache-size=# The size of file cache for the binary log --binlog-format=name What form of binary logging the master will use: either ROW for row-based binary logging, STATEMENT for statement-based binary logging, or MIXED. MIXED is statement-based binary logging except for those statements where only row-based is correct: those which involve user-defined functions (i.e. UDFs) or the UUID() function; for those, row-based binary logging is automatically used. --binlog-ignore-db=name Tells the master that updates to the given database should not be logged to the binary log. --binlog-optimize-thread-scheduling Run fast part of group commit in a single thread, to optimize kernel thread scheduling. On by default. Disable to run each transaction in group commit in its own thread, which can be slower at very high concurrency. This option is mostly for testing one algorithm versus the other, and it should not normally be necessary to change it. (Defaults to on; use --skip-binlog-optimize-thread-scheduling to disable.) --binlog-row-event-max-size=# The maximum size of a row-based binary log event in bytes. Rows will be grouped into events smaller than this size if possible. The value has to be a multiple of 256. --binlog-row-image=name Controls whether rows should be logged in 'FULL', 'NOBLOB' or 'MINIMAL' formats. 'FULL', means that all columns in the before and after image are logged. 'NOBLOB', means that mysqld avoids logging blob columns whenever possible (eg, blob column was not changed or is not part of primary key). 'MINIMAL', means that a PK equivalent (PK columns or full row if there is no PK in the table) is logged in the before image, and only changed columns are logged in the after image. (Default: FULL). --binlog-row-metadata=name Controls whether metadata is logged using FULL , MINIMAL format and NO_LOG.FULL causes all metadata to be logged; MINIMAL means that only metadata actually required by slave is logged; NO_LOG NO metadata will be logged.Default: NO_LOG. --binlog-stmt-cache-size=# The size of the statement cache for updates to non-transactional engines for the binary log. If you often use statements updating a great number of rows, you can increase this to get more performance. --bootstrap Used by mysql installation scripts. --bulk-insert-buffer-size=# Size of tree cache used in bulk insert optimisation. Note that this is a limit per thread! --character-set-client-handshake Don't ignore client side character set value sent during handshake. (Defaults to on; use --skip-character-set-client-handshake to disable.) --character-set-filesystem=name Set the filesystem character set. -C, --character-set-server=name Set the default character set. --character-sets-dir=name Directory where character sets are -r, --chroot=name Chroot mysqld daemon during startup. --collation-server=name Set the default collation. --column-compression-threshold=# Minimum column data length eligible for compression --column-compression-zlib-level=# zlib compression level (1 gives best speed, 9 gives best compression) --column-compression-zlib-strategy=name The strategy parameter is used to tune the compression algorithm. Use the value DEFAULT_STRATEGY for normal data, FILTERED for data produced by a filter (or predictor), HUFFMAN_ONLY to force Huffman encoding only (no string match), or RLE to limit match distances to one (run-length encoding). Filtered data consists mostly of small values with a somewhat random distribution. In this case, the compression algorithm is tuned to compress them better. The effect of FILTERED is to force more Huffman coding and less string matching; it is somewhat intermediate between DEFAULT_STRATEGY and HUFFMAN_ONLY. RLE is designed to be almost as fast as HUFFMAN_ONLY, but give better compression for PNG image data. The strategy parameter only affects the compression ratio but not the correctness of the compressed output even if it is not set appropriately. FIXED prevents the use of dynamic Huffman codes, allowing for a simpler decoder for special applications. --column-compression-zlib-wrap Generate zlib header and trailer and compute adler32 check value. It can be used with storage engines that don't provide data integrity verification to detect data corruption. --completion-type=name The transaction completion type. One of: NO_CHAIN, CHAIN, RELEASE --concurrent-insert[=name] Use concurrent insert with MyISAM. One of: NEVER, AUTO, ALWAYS --connect-timeout=# The number of seconds the mysqld server is waiting for a connect packet before responding with 'Bad handshake' --console Write error output on screen; don't remove the console window on windows. --core-file Write core on errors. -h, --datadir=name Path to the database root directory --date-format=name The DATE format (ignored) --datetime-format=name The DATETIME format (ignored) --deadlock-search-depth-long=# Long search depth for the two-step deadlock detection --deadlock-search-depth-short=# Short search depth for the two-step deadlock detection --deadlock-timeout-long=# Long timeout for the two-step deadlock detection (in microseconds) --deadlock-timeout-short=# Short timeout for the two-step deadlock detection (in microseconds) -#, --debug[=name] Built in DBUG debugger. Disabled in this build. --debug-abort-slave-event-count=# Option used by mysql-test for debugging and testing of replication. --debug-disconnect-slave-event-count=# Option used by mysql-test for debugging and testing of replication. -T, --debug-exit-info[=#] Used for debugging. Use at your own risk. --debug-gdb Set up signals usable for debugging. --debug-max-binlog-dump-events=# Option used by mysql-test for debugging and testing of replication. --debug-no-sync Disables system sync calls. Only for running tests or debugging! --debug-no-thread-alarm Disable system thread alarm calls. Disabling it may be useful in debugging or testing, never do it in production --debug-sporadic-binlog-dump-fail Option used by mysql-test for debugging and testing of replication. --default-password-lifetime=# This defines the global password expiration policy. 0 means automatic password expiration is disabled. If the value is a positive integer N, the passwords must be changed every N days. This behavior can be overridden using the password expiration options in ALTER USER. --default-regex-flags=name Default flags for the regex library. Any combination of: DOTALL, DUPNAMES, EXTENDED, EXTENDED_MORE, EXTRA, MULTILINE, UNGREEDY --default-storage-engine=name The default storage engine for new tables --default-time-zone=name Set the default time zone. --default-tmp-storage-engine=name The default storage engine for user-created temporary tables --default-week-format=# The default week format used by WEEK() functions --delay-key-write[=name] Specifies how MyISAM tables handles CREATE TABLE DELAY_KEY_WRITE. If set to ON, the default, any DELAY KEY WRITEs are honored. The key buffer is then flushed only when the table closes, speeding up writes. MyISAM tables should be automatically checked upon startup in this case, and --external locking should not be used, as it can lead to index corruption. If set to OFF, DELAY KEY WRITEs are ignored, while if set to ALL, all new opened tables are treated as if created with DELAY KEY WRITEs enabled. --delayed-insert-limit=# After inserting delayed_insert_limit rows, the INSERT DELAYED handler will check if there are any SELECT statements pending. If so, it allows these to execute before continuing. --delayed-insert-timeout=# How long a INSERT DELAYED thread should wait for INSERT statements before terminating --delayed-queue-size=# What size queue (in rows) should be allocated for handling INSERT DELAYED. If the queue becomes full, any client that does INSERT DELAYED will wait until there is room in the queue again --des-key-file=name Load keys for des_encrypt() and des_encrypt from given file. --disconnect-on-expired-password This variable controls how the server handles clients that are not aware of the sandbox mode. If enabled, the server disconnects the client, otherwise the server puts the client in a sandbox mode. --div-precision-increment=# Precision of the result of '/' operator will be increased on that value --encrypt-binlog Encrypt binary logs (including relay logs) --encrypt-tmp-disk-tables Encrypt temporary on-disk tables (created as part of query execution) --encrypt-tmp-files Encrypt temporary files (created for filesort, binary log cache, etc) --enforce-storage-engine=name Force the use of a storage engine for new tables --eq-range-index-dive-limit=# The optimizer will use existing index statistics instead of doing index dives for equality ranges if the number of equality ranges for the index is larger than or equal to this number. If set to 0, index dives are always used. --event-scheduler[=name] Enable the event scheduler. Possible values are ON, OFF, and DISABLED (keep the event scheduler completely deactivated, it cannot be activated run-time) --expensive-subquery-limit=# The maximum number of rows a subquery may examine in order to be executed during optimization and used for constant optimization --expire-logs-days=# If non-zero, binary logs will be purged after expire_logs_days days; possible purges happen at startup and at binary log rotation --explicit-defaults-for-timestamp This option causes CREATE TABLE to create all TIMESTAMP columns as NULL with DEFAULT NULL attribute, Without this option, TIMESTAMP columns are NOT NULL and have implicit DEFAULT clauses. --external-locking Use system (external) locking (disabled by default). With this option enabled you can run myisamchk to test (not repair) tables while the MySQL server is running. Disable with --skip-external-locking. --extra-max-connections=# The number of connections on extra-port --extra-port=# Extra port number to use for tcp connections in a one-thread-per-connection manner. 0 means don't use another port --feedback[=name] Enable or disable FEEDBACK plugin. One of: ON, OFF, FORCE (don't start if the plugin fails to load), FORCE_PLUS_PERMANENT (like FORCE, but the plugin can not be uninstalled). --feedback-http-proxy=name Proxy server host:port. --feedback-send-retry-wait=# Wait this many seconds before retrying a failed send. --feedback-send-timeout=# Timeout (in seconds) for the sending the report. --feedback-url=name Space separated URLs to send the feedback report to. --feedback-user-info=name User specified string that will be included in the feedback report. --flashback Setup the server to use flashback. This enables binary log in row mode and will enable extra logging for DDL's needed by flashback feature --flush Flush MyISAM tables to disk between SQL commands --flush-time=# A dedicated thread is created to flush all tables at the given interval --ft-boolean-syntax=name List of operators for MATCH ... AGAINST ( ... IN BOOLEAN MODE) --ft-max-word-len=# The maximum length of the word to be included in a FULLTEXT index. Note: FULLTEXT indexes must be rebuilt after changing this variable --ft-min-word-len=# The minimum length of the word to be included in a FULLTEXT index. Note: FULLTEXT indexes must be rebuilt after changing this variable --ft-query-expansion-limit=# Number of best matches to use for query expansion --ft-stopword-file=name Use stopwords from this file instead of built-in list --gdb Set up signals usable for debugging. Deprecated, use --debug-gdb instead. --general-log Log connections and queries to a table or log file. Defaults logging to a file 'hostname'.log or a table mysql.general_logif --log-output=TABLE is used. --general-log-file=name Log connections and queries to given file --getopt-prefix-matching Recognize command-line options by their unambiguos prefixes. (Defaults to on; use --skip-getopt-prefix-matching to disable.) --group-concat-max-len=# The maximum length of the result of function GROUP_CONCAT() --gtid-cleanup-batch-size=# Normally does not need tuning. How many old rows must accumulate in the mysql.gtid_slave_pos table before a background job will be run to delete them. Can be increased to reduce number of commits if using many different engines with --gtid_pos_auto_engines, or to reduce CPU overhead if using a huge number of different gtid_domain_ids. Can be decreased to reduce number of old rows in the table. --gtid-domain-id=# Used with global transaction ID to identify logically independent replication streams. When events can propagate through multiple parallel paths (for example multiple masters), each independent source server must use a distinct domain_id. For simple tree-shaped replication topologies, it can be left at its default, 0. --gtid-ignore-duplicates When set, different master connections in multi-source replication are allowed to receive and process event groups with the same GTID (when using GTID mode). Only one will be applied, any others will be ignored. Within a given replication domain, just the sequence number will be used to decide whether a given GTID has been already applied; this means it is the responsibility of the user to ensure that GTID sequence numbers are strictly increasing. --gtid-pos-auto-engines=name List of engines for which to automatically create a mysql.gtid_slave_pos_ENGINE table, if a transaction using that engine is replicated. This can be used to avoid introducing cross-engine transactions, if engines are used different from that used by table mysql.gtid_slave_pos --gtid-strict-mode Enforce strict seq_no ordering of events in the binary log. Slave stops with an error if it encounters an event that would cause it to generate an out-of-order binlog if executed. -?, --help Display this help and exit. --histogram-size=# Number of bytes used for a histogram.

(Automatically configured unless set explicitly) --idle-readonly-transaction-timeout=# The number of seconds the server waits for read-only idle transaction --idle-transaction-timeout=# The number of seconds the server waits for idle transaction --idle-write-transaction-timeout=# The number of seconds the server waits for write idle transaction --ignore-builtin-innodb Disable initialization of builtin InnoDB plugin --ignore-db-dirs=name Specifies a directory to add to the ignore list when collecting database names from the datadir. Put a blank argument to reset the list accumulated so far. --in-predicate-conversion-threshold=# The minimum number of scalar elements in the value list of IN predicate that triggers its conversion to IN subquery. Set to 0 to disable the conversion. --init-connect=name Command(s) that are executed for each new connection (unless the user has SUPER privilege) --init-file=name Read SQL commands from this file at startup --init-rpl-role=name Set the replication role.

One of: ON, OFF, FORCE (don't start if the plugin fails to load), FORCE_PLUS_PERMANENT (like FORCE, but the plugin can not be uninstalled). --innodb-adaptive-flushing Attempt flushing dirty pages to avoid IO bursts at checkpoints. (Defaults to on; use --skip-innodb-adaptive-flushing to disable.) --innodb-adaptive-flushing-lwm=# Percentage of log capacity below which no adaptive flushing happens. --innodb-adaptive-hash-index Enable InnoDB adaptive hash index (disabled by default). --innodb-adaptive-hash-index-parts[=#] Number of InnoDB Adaptive Hash Index Partitions (default 8) --innodb-adaptive-max-sleep-delay=# The upper limit of the sleep delay in usec. Value of 0 disables it. --innodb-autoextend-increment=# Data file autoextend increment in megabytes --innodb-autoinc-lock-mode=# The AUTOINC lock modes supported by InnoDB: 0 => Old style AUTOINC locking (for backward compatibility); 1 => New style AUTOINC locking; 2 => No AUTOINC locking (unsafe for SBR) --innodb-background-scrub-data-check-interval=# Deprecated parameter with no effect. --innodb-background-scrub-data-compressed Deprecated parameter with no effect. --innodb-background-scrub-data-interval=# Deprecated parameter with no effect. --innodb-background-scrub-data-uncompressed Deprecated parameter with no effect. --innodb-buf-dump-status-frequency=# A number between [0, 100] that tells how oftern buffer pool dump status in percentages should be printed. E.g. 10 means that buffer pool dump status is printed when every 10% of number of buffer pool pages are dumped.

One of: ON, OFF, FORCE (don't start if the plugin fails to load), FORCE_PLUS_PERMANENT (like FORCE, but the plugin can not be uninstalled). --innodb-change-buffer-max-size=# Maximum on-disk size of change buffer in terms of percentage of the buffer pool. --innodb-change-buffering=name Buffer changes to secondary indexes.. One of: none, inserts, deletes, changes, purges, all --innodb-checksum-algorithm=name The algorithm InnoDB uses for page checksumming. Possible values are FULL_CRC32 for new files, always use CRC-32C; for old, see CRC32 below; STRICT_FULL_CRC32 for new files, always use CRC-32C; for old, see STRICT_CRC32 below; CRC32 write crc32, allow any of the other checksums to match when reading; STRICT_CRC32 write crc32, do not allow other algorithms to match when reading; INNODB write a software calculated checksum, allow any other checksums to match when reading; STRICT_INNODB write a software calculated checksum, do not allow other algorithms to match when reading; NONE write a constant magic number, do not do any checksum verification when reading (same as innodb_checksums=OFF); STRICT_NONE write a constant magic number, do not allow values other than that magic number when reading; Files updated when this option is set to crc32 or strict_crc32 will not be readable by MariaDB versions older than 10.0.4; new files created with full_crc32 are readable by MariaDB 10.4.3+ --innodb-cmp[=name] Enable or disable INNODB_CMP plugin. One of: ON, OFF, FORCE (don't start if the plugin fails to load), FORCE_PLUS_PERMANENT (like FORCE, but the plugin can not be uninstalled). --innodb-cmp-per-index[=name] Enable or disable INNODB_CMP_PER_INDEX plugin.

One of: ON, OFF, FORCE (don't start if the plugin fails to load), FORCE_PLUS_PERMANENT (like FORCE, but the plugin can not be uninstalled). --innodb-commit-concurrency=# Helps in performance tuning in heavily concurrent environments. --innodb-compression-algorithm[=name] Compression algorithm used on page compression. One of: none, zlib, lz4, lzo, lzma, or bzip2 --innodb-compression-default Is compression the default for new tables --innodb-compression-failure-threshold-pct[=#] If the compression failure rate of a table is greater than this number more padding is added to the pages to reduce the failures.

Possible values are REDUNDANT, COMPACT, and DYNAMIC. The ROW_FORMAT value COMPRESSED is not allowed. One of: redundant, compact, dynamic --innodb-defragment Enable/disable InnoDB defragmentation (default FALSE). When set to FALSE, all existing defragmentation will be paused. And new defragmentation command will fail.Paused defragmentation commands will resume when this variable is set to true again. --innodb-defragment-fill-factor=# A number between [0.7, 1] that tells defragmentation how full it should fill a page. Default is 0.9. Number below 0.7 won't make much sense.This variable, together with innodb_defragment_fill_factor_n_recs, is introduced so defragmentation won't pack the page too full and cause page split on the next insert on every page. The variable indicating more defragmentation gain is the one effective. --innodb-defragment-fill-factor-n-recs=# How many records of space defragmentation should leave on the page. This variable, together with innodb_defragment_fill_factor, is introduced so defragmentation won't pack the page too full and cause page split on the next insert on every page. The variable indicating more defragmentation gain is the one effective. --innodb-defragment-frequency=# Do not defragment a single index more than this number of time per second.This controls the number of time defragmentation thread can request X_LOCK on an index. Defragmentation thread will check whether 1/defragment_frequency (s) has passed since it worked on this index last time, and put the index back to the queue if not enough time has passed. The actual frequency can only be lower than this given number. --innodb-defragment-n-pages=# Number of pages considered at once when merging multiple pages to defragment --innodb-defragment-stats-accuracy=# How many defragment stats changes there are before the stats are written to persistent storage.

When using multiple domains, this can be used to limit a single domain from grabbing all threads and thus stalling other domains. The default of 0 means to allow a domain to grab as many threads as it wants, up to the value of slave_parallel_threads. --slave-exec-mode=name How replication events should be executed. Legal values are STRICT (default) and IDEMPOTENT. In IDEMPOTENT mode, replication will not stop for operations that are idempotent. For example, in row based replication attempts to delete rows that doesn't exist will be ignored. In STRICT mode, replication will stop on any unexpected difference between the master and the slave. --slave-load-tmpdir=name The location where the slave should put its temporary files when replicating a LOAD DATA INFILE command --slave-max-allowed-packet=# The maximum packet length to sent successfully from the master to slave. --slave-net-timeout=# Number of seconds to wait for more data from any master/slave connection before aborting the read --slave-parallel-max-queued=# Limit on how much memory SQL threads should use per parallel replication thread when reading ahead in the relay log looking for opportunities for parallel replication.

YES and LOGGING means that triggers will be running on slave, if there was not triggers running on the master for the statement. LOGGING also means results of that the executed triggers work will be written to the binlog. ENFORCE means that triggers will always be run on the slave, even if there are triggers on the master. ENFORCE implies LOGGING. --slave-skip-errors=name Tells the slave thread to continue replication when a query event returns an error from the provided list --slave-sql-verify-checksum Force checksum verification of replication events after reading them from relay log.
