scwhittle opened a new pull request #13862: URL: https://github.com/apache/beam/pull/13862
… upon
reference invalidation instead of expensive set management. Reduce
operations of shared cache by caching per-key object sets locally and
flushing as groups to shared cache. Remove byte tracking which could
be racy based upon background evictions in favor of just iterating
for rendering the status page. Since we render only once every 10 minutes
by default this seems fine.
This also lets us capture more stats.
This previously showed up as 6% cpu on benchmarks and dropped to 1.25% with
this change with throughput increase as well.
