Innodb日志刷新以防止数据丢失

Question

I need to have a high power fault tollerance to my innodb engine and i can not change hardware configuration. Do you suggest to call

FLUSH ENGINE LOGS;

after a very important operations? Can it help to prevent data loss from poweroff or process crash?

Answer 1

Using FLUSH ENGINE LOGS should be unnecessary. Your configuration of MySQL/InnoDB should have:

• innodb_flush_logs_at_trx_commit = 1
• sync_binlog = 1

Beyond that, if your hardware is not reliable, there's not much that can be done.
