What's New At Releem | August 2022

Releem is a continuous work in progress because we have a long list of features and improvements we’d like to make to add. This is part of our commitment to providing an excellent product to our customers. For the month of August, we’re most excited to announce our new one-step command for applying configuration recommendations. We’ve also added new variables and refined the signup and login process.

We're super happy to announce that we've added a simple command that applies the recommended MySQL configuration. This feature has been in the works for a while now, and we are finally ready to release it to our customers.

This new command will significantly reduce the time it takes to apply recommended configurations.

Also, we've added a new command to roll back to previous configurations. It'll significantly reduce the rollback operation's time if the previous configuration works better.

To ensure this feature is robust, we built a test platform for Releem Agent using AWS, CloudFormation, and Ansible. It's been tested on Debian (10,11) and CentOS (7,8) to work with the following server versions:

• MariaDB (10.X)
• MySQL 5.7, 8.0
• Percona 5.7, 8.0

Please update Releem Agent on your servers, and follow the documentation to use the "apply" and "rollback" commands.

We aim to add more configuration variables each month to bring the best performance to your database servers, and this month, we’ve added innodb_page_cleaners and innodb_purge_threads. These new variables help make better configuration recommendations. Now Releem supports 35 MySQL variables.

The innodb_page_cleaners variable sets the number of page cleaner threads.

The innodb_purge_threads variable is the number of background threads dedicated to InnoDB purge operations. This variable can be set to a value from 1 to 32. For example, if innodb_purge_threads is set to 12, there are 12 separate purge threads.
