And are also both Keycloak nodes in the same infinispan cluster?

We've got synchronous replication enabled. I've looked in the
DB
tables for both galera nodes and the data is there. e.g. both DB nodes
have client 'myclient' but the UI for Keycloak node 2 doesn't list a
'myclient'. But Keycloak will error if you try to add 'myclient'
saying it already exists.

caching...
Do you have DB configured with synchronous replication (eg.
inserting some record on DB1 is successfully finished after the
record is successfully replicated to DB2 too) ?
You can maybe compare with the configuration in my docker image
https://github.com/mposolda/keycloak-mariadb
<https://github.com/mposolda/keycloak-mariadb> . I can't recall to
see any issue like this, but not sure about other aspects of my
configuration (performance etc).
