Which Indexes are Cached? Discover with PMM.

One of the great things about working at Percona is the constant innovation that occurs as a result of a deep level of technical expertise.

Data is accessed significantly faster when it is cached, so indexes that are cached will allow for an increase in query performance. Until now there has not been an easy way to see which indexes are cached and which are not. We want to take the …

MySQL 8 and MySQL 5.7 Memory Consumption on Small Devices

While we often run MySQL on larger scale systems in Production for Test and Dev, sometimes we want to run MySQL on the tiniest cloud instances possible or just run it on our laptops. In these cases, MySQL 8 and MySQL 5.7 memory consumption is quite important.

In comparing MySQL 8 vs MySQL 5.7, you should know that MySQL 8 uses more memory. Basic tests on a 1GB VM with MySQL 8 and MySQL 5.7 (actually they’re Percona Server versions) running the same light workload, I see the following vmstat output:
