    • Type: Improvement
    • Status: Resolved
    • Priority: Major
    • Resolution: Won't Fix
    • Affects Version/s: Impala 2.6.0
    • Fix Version/s: None
    • Component/s: Catalog

      Description

      It is difficult to tune and debug the Catalog performance as it doesn't expose any metrics indicating the current state.

      The Catalog should expose object count and estimate memory consumed by each object type

      • Partitions
      • Files
      • Blocks

      A breakdown per DB/Table/Partition would be ideal.

      Also a measure of heap usage by the JVM along with GC time as a % of the JVM lifetime.
