I=E2=80=99m attempting to configure a cluster of standalone Keycloak 4.7.0.= Final instances to have their Infinispan data persisted. I=E2=80=99m using = JDBCPING to create the cluster, and our user load is great enough that we d= on=E2=80=99t want to keep all our sessions in memory. I=E2=80=99ve configured the =E2=80=9Csessions=E2=80=9D cache as follows:
The object-memory size is selected purely for testing purposes, so that I c= an quickly hit a point where data will need to be evicted from Infinispan. The problem I=E2=80=99m running into is that data is only persisted to MySQ= L is passivation is on, where it exhibits the predictable passivation behav= iour. When I turn passivation to false, instead of acting as a write-throug= h cache, will all data persisted, no data is persisted at all. Once I fill = the object-memory size, sessions start getting dropped behind the scenes. Is this pilot error? Or have I found a bug in Infinispan? DEBUG-level loggi= ng doesn=E2=80=99t reveal any complaints from the underlying systems. Thanks!

DEBUG-level log= ging doesn=E2=80=99t reveal any complaints from the underlying systems. We're programatically adding the flag to skip cacheStore/cacheLoad to = many operations on userSession. The reason is, that for cross-dc = scenario, we're programatically invoking execution of some operations on = remote caches (JDG servers). In other words, no other infinispan stores besides remote-store will = properly work. Feel free to create JIRA (or add yourself as a vote to = existing JIRA as it maybe already exists).
