This feature is intended to provide a general mechanism (using log_warnings_silence) to disable certain warning messages to the log file. Currently, it is only implemented for disabling message #1592 warnings. This feature does not influence warnings delivered to a client.
(empty string), 1592
This variable was added in beta release 5.5.8-20.0 as log_warnings_silence and renamed in release 5.5.10-20.1.
It is intended to provide a more general mechanism for disabling warnings than existed previously with variable suppress_log_warning_1592.
When set to the empty string, no warnings are disabled. When set to 1592, warning #1592 messages (unsafe statement for binary logging) are suppressed.
In the future, the ability to optionally disable additional warnings may also be added.
