> Project: Beam
> Issue Type: Bug
> Components: runner-dataflow
> Affects Versions: 2.29.0
> Reporter: Steve Niemitz
> Assignee: Kenneth Knowles
> Priority: P1
> Fix For: 2.30.0
>
>
> 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.
