Summary: LLAP: switch to sensible cache policy
Key: HIVE-10155
URL: https://issues.apache.org/jira/browse/HIVE-10155
Project: Hive
Issue Type: Sub-task
Reporter: Sergey Shelukhin
Assignee: Sergey Shelukhin
FIFO policy is currently the default. We can test LRFU one but there were
concerns that it won't scale. One option is to implement a two-tier policy,
FIFO/LRU for blocks referenced once, and something more complex (LFU, LRFU) for
blocks referenced more than once. That should be friendly to large scans of a
fact table in terms of behavior and overhead.
