MySQL 1559

This error occurs when attempting to switch out of row-based replication (RBR) while a temporary table exists. MySQL 1559 prevents this action and requires the temporary table to be dropped before switching out of RBR.

How It Affects Your App

This error indicates that a temporary table is preventing the switch out of row-based replication (RBR). This can have a significant impact on an application as it can prevent the application from performing certain operations. It can also lead to data inconsistency between the master and slave databases, as the slave will not be able to replicate the changes made on the master. This can lead to data loss or corruption, which can have serious consequences for the application.

How To Fix

1. Check the error log for the MySQL 1559 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations:
$ cat /etc/mysql/my.cnf
3. Check the MySQL server status to see if it is running:
$ mysqladmin status
4. Check the MySQL server version to ensure it is up to date:
$ mysqladmin version
5. Check the MySQL server process list to see if there are any long-running queries:
$ mysqladmin processlist
6. Check the MySQL server variables to see if any of them are set incorrectly:
$ mysqladmin variables
7. Check the MySQL server logs for any suspicious activity:
$ tail -f /var/log/mysql/mysql.log
8. Restart the MySQL server to apply any changes made to the configuration file:
$ service mysql restart
9. Use an automated database observability tool to monitor and fix the MySQL 1559 in question. Automated database observability tools can provide real-time insights into the performance and health of your database, allowing you to quickly identify and fix any issues that may arise. They can also provide detailed metrics and logs that can help you diagnose and troubleshoot any issues that may arise.
