MySQL Error 1197: Binlog Cache Size Exceeded
Description
This error indicates that a multi-statement transaction attempted to store more data in the binary log cache than the 'max_binlog_cache_size' system variable allows. It commonly occurs during large data modification operations or complex transactions that generate extensive binary log entries.
Error Message
