Inproved redo log management

Solution 1

innodb_redo_log_file_size_extend_on_startup = 0 | 1 | 2: 0 default

1 auto_rezise
Instead of Shutdown in case of wrong redo log size rename ib_logfiles to ib_logfiles.timestamp.old

2 ignore_configuration

Ignore configuration parameter and start the server with the size of the existing redo log file

A sub task could be to check if the redo log are purged before creating them if not start innodb on the old redolog and start to apply change before creating the new redo logs

Solution 2
innodb_redo_log_file_max_size
innodb_redo_log_file_auto_extend

Like in MSSQL or Sybase the redo logs are not fixed in size and can grow to adapt for big transactions, this task would enable this as we monitor the redolog pointer we extend the redo log file size
