Summary: LLAP: Parquet caching Key: HIVE-17006 URL: https://issues.apache.org/jira/browse/HIVE-17006 Project: Hive Issue Type: Bug Reporter: Sergey Shelukhin Assignee: Sergey Shelukhin There are multiple options to do Parquet caching in LLAP: 1) Full elevator (too intrusive for now). 2) Page based cache like ORC (requires some changes to Parquet or copy-pasted). 3) Cache disk data on column chunk level as is. Given that Parquet reads at column chunk granularity, (2) is not as useful as for ORC, but still a good idea. I messaged the dev list about it but didn't get a response, we may follow up later. For now, do (3). -- This message was sent by Atlassian JIRA (v6.4.14#64029)
