Error Logging in MySQL 8

Although only available as a Release Candidate, MySQL 8 is already proving itself to be a huge leap forward in many regards. Error logging is no exception. The MySQL development team just announced that they have redesigned the error logging subsystem to use a new component architecture.

The redesign will allow the filtering of log events, as well as the routing of error log output to multiple destinations, via the enabling of multiple sink components.  This will make it possible to send error log events to third-party systems for additional formatting and analysis.

In today’s blog, we’ll explore how to employ MySQL 8’s component-based error logging to achieve a variety of logging configurations. Note that all this is specific for MySQL 8 and is not available in earlier versions and also not in MariaDB. However, MariaDB has an option to write the error log to the system “syslog” on systemd-based Linux variants – …

Binlog and Replication Improvements in Percona Server for MySQL

Due to continuous development and improvement, Percona Server for MySQL incorporates a number of improvements related to binary log handling and replication. This results in replication specifics, distinguishing it from MySQL Server.

Temporary tables and mixed logging format Summary of the fix:

As soon as some statement involving temporary tables was met when using a mixed binlog format, MySQL switched to row-based logging for all statements until the end of the session (or until all temporary tables used in the session were dropped). This is inconvenient when you have long-lasting connections, including replication-related ones. Percona Server for MySQL fixes the situation by switching between …

How to change the number or size of InnoDB Redo Log Files ?

To change the number or the size of your InnoDB redo log files, please follow the steps below:

Step 1: Stop the MySQL server and confirm that it has shutdown without any errors

Step 2: Edit my.cnf to configure innodb_log_file_size (log file size) and innodb_log_files_in_group (number of log files)

Step 3: Restart MySQL server

If ever InnoDB finds innodb_log_file_size differs from the redo log files, It writes a log checkpoint, closes and removes the old log files, create again new log files at requested size and opens the new log files.

The post How to change the number or size of InnoDB Redo Log Files ? appeared first on MySQL Consulting, …
