MySQL error 1197 signals that a single transaction exceeded the max_binlog_cache_size, exhausting the binary log cache.
MySQL Error 1197: ER_TRANS_CACHE_FULL occurs when a transaction needs more space than max_binlog_cache_size permits. Increase max_binlog_cache_size or refactor the transaction to use smaller statements to resolve the issue.
ER_TRANS_CACHE_FULL
The message "Multi-statement transaction required more than 'max_binlog_cache_size' bytes of storage" tells MySQL that the binary log cache ran out of space for the current transaction.
During a transaction, MySQL writes each statement to an in-memory binary log cache. If the total size grows beyond max_binlog_cache_size, the server raises error 1197 and rolls the transaction back to protect data integrity.
Binary logs are essential for replication and crash recovery.
Hitting the cache limit means the transaction cannot be fully logged, so MySQL aborts it rather than risk data loss on replicas or during recovery.
Error 1197 appears in MySQL 5.6, 5.7, 8.0, and MariaDB variants that support binary logging.
The default cache limit is 32 MiB before MySQL 8.0.14 and 256 MiB afterward, but large bulk inserts can still exceed it.

.
Yes, as long as the server has enough memory. Monitor RAM usage and set a limit that balances performance and safety.
You can, but you lose replication and point-in-time recovery. Only disable logging for isolated maintenance loads.
Yes. When the cache limit is reached, MySQL aborts and rolls back the transaction to maintain consistency.
Galaxy’s AI copilot flags transactions likely to exceed cache limits and suggests chunking or limit adjustments during query authoring.
