It sounds like you’re running this mostly on a single machine? Temporal gets much more complex with scale. Cassandra isn’t fun to manage. Ringpop and TChannel are hard to debug when things go wrong. The SQL backend support doesn’t support horizontally scaled replicas (just single instance) due to consistency requirements. Depending on how your code is written, modifying code baked into workflows becomes complex, as anything that modifies the history event ordering breaks determinism in already-deployed workers.

We use it heavily and everyone who started on it doing simple scripting/automation all love it, everyone who built real production systems on top of it all hate it. Possibly operator error, but my experience hasn’t matched the rosy picture painted in these comments.
