Member Function Documentation

◆ finalize() [1/2]

int binlog_cache_data::finalize	(	THD *	thd,
		Log_event *	end_event
	)

This function finalizes the cache preparing for commit or rollback.

The function just writes all the necessary events to the cache but does not flush the data to the binary log file. That is the role of the binlog_cache_data::flush function.

See also: binlog_cache_data::flush

Parameters

thd	The thread whose transaction should be flushed
end_event	The end event either commit/rollback

Returns: nonzero if an error pops up when flushing the cache.

◆ finalize() [2/2]

int binlog_cache_data::finalize	(	THD *	thd,
		Log_event *	end_event,
		XID_STATE *	xs
	)

The method writes XA END query to XA-prepared transaction's cache and calls the "basic" finalize().

Returns: error code, 0 success
