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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
