Kenneth Knowles commented on BEAM-12229:
----------------------------------------
Yes, it was addressed by that. It is fixed on master. I have also backported
the fix to apply to the internal Dataflow container image. We should also
cherrypick to the 2.29.0 release branch actually, so that if anyone cuts 2.29.1
it is still included. That can be its own Jira. Actually let me put this one
back to 2.30.0 and open the cherrypick Jira.

> 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.
