    Description

      Using jemalloc with mysqld is known to fix some memory leaks. It's often a recommended practice to try using an alternative allocator library in case the memory usage is suspected to be higher than expected.

      It should be possible to opt into using jemalloc for mysqld in the operator-controlled clusters. All PXC images come bundled with jemalloc: https://github.com/percona/percona-docker/blob/main/percona-xtradb-cluster-5.7/Dockerfile.k8s#L66, so using it is a matter of configuration.

       

      We are going to allow to pass environment variables through Secrets to MySQL. This will allow users to control various parameters, including LD_PRELOAD.
