> LLAP: monitoring and better default lambda for LRFU policy
> ----------------------------------------------------------
>
> Key: HIVE-16992
> URL: https://issues.apache.org/jira/browse/HIVE-16992
> Project: Hive
> Issue Type: Sub-task
> Reporter: Sergey Shelukhin
> Assignee: Sergey Shelukhin
> Priority: Major
> Attachments: HIVE-16992.patch
>
>
> LRFU is currently skewed heavily towards LRU; there are 10k-s or 100k-s of
> buffers tracked during a typical workload, but the heap size is around 700.
> We should see if making it closer to LFU (by tweaking the lambda) will
> improve hit rate with small queries infrequently interleaved with large
> scans; and whether it will have negative effects due to perf overhead.
