Test MariaDB 10.4 in production
Open, Needs TriagePublic


db1107 has been running 10.4 for a few weeks (replicating to a Percona 8 slave with no issue).
We've not seen any replication issues.

We should replay some production queries into it to make sure nothing shows up and if so, let's reimage db1107 and place it somewhere in production with very low weight to see how it performs.
