Multi master replication and deadlock detection in Galera with Mariadbs
Hi,
We have multi master Galera replication setup where three master mariadbs are continuously updated. 1. Because of which occasionally a transaction encounters deadlock. 2. The JDBC queries slow down their executions if we allow continuous table updates.
Add to the mix an event that purges the tables and we noticed a deletion of more than 200000 entries held the lock for more than 15 seconds.
How can we rectify this problem? Is there a way to improve DB performance in replication setup? We also used non replicated setup and the portal does not encounter any JDBC connection errors.
Your insights are much appreciated.
Thanks
