[jira] [Issue Comment Deleted] (HIVE-15988) LLAP: cache ORC ACID deltas

     [ https://issues.apache.org/jira/browse/HIVE-15988?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Teddy Choi updated HIVE-15988:
------------------------------
    Comment: was deleted

(was: HIVE-12631 implemented ORC ACID table support in LLAP. If we cache ACID delta in LLAP, it will be faster.

The cache is currently low-level (CB-level in ORC), so we could just use it to read bases and deltas (deltas should be cached with higher priority) and merge as usual. We could also cache merged representation in future.)
