MySQL 135

This error occurs when a query is executed that requires an index to be present in the table, but no such index exists. MySQL 135 indicates that the query cannot be completed due to the lack of an index in the table that fits the column list.

How It Affects Your App

MySQL 135 is an error that occurs when a table does not have an index that fits the column list on the application. This can have a significant impact on the performance of the application, as it can cause queries to take longer to execute. Without an index, the database must search through all of the data in the table to find the requested information, which can be time consuming. Additionally, the lack of an index can lead to data integrity issues, as the database may not be able to guarantee the accuracy of the data it returns.

How To Fix

1. Check the error log for the MySQL 135 instance to identify the root cause of the issue.

$ sudo tail -f /var/log/mysql/error.log

2. Check the configuration of the MySQL 135 instance to identify any misconfigurations.

$ sudo cat /etc/mysql/my.cnf

3. Check the status of the MySQL 135 instance to identify any issues with the running processes.

$ sudo systemctl status mysql

4. Check the system resources to identify any resource constraints that may be causing the issue.

$ sudo top

5. Check the network connections to identify any network issues that may be causing the issue.

$ sudo netstat -an

6. Once the root cause of the issue has been identified, take the necessary steps to fix the issue.7. After the issue has been fixed, restart the MySQL 135 instance to ensure that the issue has been resolved.

$ sudo systemctl restart mysql

8. Finally, it is recommended to use an automated database observability tool to monitor and fix the MySQL 135 instance in question.
