Hi all, This morning I had to fix up a cluster of NiFi 1.18.0 servers where the primary was constantly crashing and moving to the next server.
One of the recent changes was activating an Embedded Hazelcast Cache, and I did see errors reported trying with promotions going wrong. I can’t tell if this is cause or effect, so I’m trying to get a feeling for the performance demands of Hazelcast, but there is nothing, only a time to live for cache items. The diagnostics dump also didn’t give me anything on this controllerservice. Does anyone have experience with tuning/diagnosing the Hazelcast components within NiFi?
