In this post, we’ll discuss how MySQL 5.7 handles the old temporal types during an upgrade.

MySQL changed the temporal types in MySQL 5.6.4, and it introduced a new feature: microseconds resolution in the TIME, TIMESTAMP and DATETIME types. Now these parameters can be set down to microsecond granularity. Obviously, this means format changes, but why is this important?

Are they converted automatically to the new format?

In this blog post, we’ll discuss upgrading MySQL with Orchestrator.

I recently had a client, Life360, that wanted to upgrade from Percona Server 5.5 to Percona Server 5.6, and implement GTID in their high transaction environment. They had co-masters and multiple read slaves.

In this blog post, we’ll discuss some of the basics regarding Docker MySQL replication. Docker has gained widespread popularity in recent years as a lightweight alternative to virtualization. It is ideal for building virtual development and testing environments. The solution is flexible and seamlessly integrates with popular CI tools.

You can add whatever other variables you want to override in the configuration files for each instance.

Note: the configuration described here is suitable for development or testing. We’ve also used the …

Starting from the Percona Server 5.6 release, we’ve introduced several significant changes that help address performance problems for highly-concurrent I/O-bound workloads. Some of our research and improvements were re-implemented for MySQL 5.7 – one of the best MySQL releases. But even though MySQL 5.7 showed progress in various aspects of scalability and performance, we’ve found that it’s possible to push I/O bound workload limits even further.

Percona Server 5.7.11 currently has two major performance features in this area:
