Port binlog_error_action from MySQL

    XMLWordPrintable

    Details

      Description

      MySQL has had the binlog_error_action variable since MySQL 5.6.22:

      binlog_error_action

      Property Value
      Command-Line Format --binlog-error-action[=value]
      Introduced 5.6.22
      System Variable binlog_error_action
      Scope Global
      Dynamic Yes
      Type Enumeration
      Default Value IGNORE_ERROR
      Valid Values
      IGNORE_ERROR
      ABORT_SERVER

      Controls what happens when the server cannot write to the binary log, which can cause the master's log to become inconsistent and replication slaves to lose synchronization. Previous releases used the name binlogging_impossible_mode.

      In MySQL 5.6, the default for binlog_error_action is IGNORE_ERROR, meaning the server logs the error, halts logging, and continues performing updates; this is to provide backward compatibility with older versions of the MySQL Server. Setting this variable to ABORT_SERVER makes the server halt logging and shut down whenever it cannot write to the binary log; this is the recommended setting, particularly in complex replication environments.

      Is it worth porting to MariaDB?

      I think binlog_error_action=ABORT_SERVER would probably be most useful to prevent issues in complex replication environments where some errors such as full disk can cause binary logging to be completely disabled, which means that transactions which have been committed to the local server won't be able to get replication to any of the system's slaves.
