So tonight, after 2 weekend on-call shifts in a row I want to summarize what I lost over that 5 years and what I won.I never planned to leave Percona after just… Read more

We see quite often customers complaining that their Galera Cluster is not stable and "crashes" from time to time. As always one has to investigate before rating. What comes out quite often is that the customer (or better their developers) are running huge transactions. In general transactional database do NOT like huge transactions because of various reasons (MVCC, ROLLBACK, UNDO, Locking etc.). They can do it. But they are not quite good in doing it and they do not like it. Instead you should better do many smaller transactions which you can run in parallel to keep the throughput. But:… Read more

The Problem HELP, HELP! My Percona XtraDB Cluster version: 5.7.31-31. Single Node is stuck in a joined state. I recently had the privilege to help a client with a fascinating issue.
