Sergey Shelukhin updated HIVE-10155: ------------------------------------ Target Version/s: 2.0.0 > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
