[jira] [Created] (HIVE-13920) LLAP: pre-populate CVB cache

Sergey Shelukhin created HIVE-13920:

             Summary: LLAP: pre-populate CVB cache
                 Key: HIVE-13920
                 URL: https://issues.apache.org/jira/browse/HIVE-13920
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin


To avoid allocations on the main path, we should pre-populate the CVB cache. The main difficulty is propagating column indexes earlier to allocate correct vectors.
