How It Affects Your App
MySQL 1564 ER_PARTITION_FUNCTION_IS_NOT_ALLOWED indicates that the partition function used in the query is not allowed. This error can prevent the application from executing the query and thus prevent the application from performing the desired task. It can also lead to unexpected results if the query is executed without the partition function. This can cause data inconsistency and incorrect results. It can also lead to application crashes and data loss.
How To Fix
1. Check the error log for the MySQL 1564 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 process list to see if there are any long-running queries:
$ mysqladmin processlist
5. Check the MySQL server variables to see if any of them are set incorrectly:
$ mysqladmin variables
6. Check the MySQL server tables to see if any of them are corrupted:
$ mysqldump --all-databases > dump.sql
7. Use an automated database observability tool to monitor and fix the MySQL 1564 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. Additionally, these tools can provide detailed metrics and logs that can help you diagnose and troubleshoot any issues that may arise.
