[jira] [Created] (IMPALA-9698) Filemetadata loader should avoid recursing into out of range writeId directories

Vihang Karajgaonkar created IMPALA-9698:
-------------------------------------------

             Summary: Filemetadata loader should avoid recursing into out of range writeId directories
                 Key: IMPALA-9698
                 URL: https://issues.apache.org/jira/browse/IMPALA-9698
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Vihang Karajgaonkar
            Assignee: Vihang Karajgaonkar


Currently by default the FileMetadataLoader in Catalogd recurses into partition directories to load the file metadata. However, in case of transactional tables, many of such directories could be out of scope for the ValidWriteList of that table when the load is happening. Avoiding to recurse in such directories could help speed up the file-metadata load on transactional tables when compaction is not being run for longer durations.
