------------------------------------
Summary: WindmillStateCache has a 0% hit rate in 2.29
Key: BEAM-12229
URL: https://issues.apache.org/jira/browse/BEAM-12229
Project: Beam
Issue Type: Bug
Components: runner-dataflow
Affects Versions: 2.29.0
Reporter: Steve Niemitz
Assignee: Reuven Lax
After upgrading to 2.29, I noticed that our jobs have a 0% state cache hit
rate. I see a very high eviction rate from the cache as well (it used to be
~0, now its ~100,000+ evictions / second).
We never were on 2.28, so I can't say if it worked there, but it did work on
2.27.
