----------------------------------------
Summary: Apply optimization in IMPALA-7320 during event processing
Key: IMPALA-12456
URL: https://issues.apache.org/jira/browse/IMPALA-12456
Project: IMPALA
Issue Type: Improvement
Components: Catalog
Reporter: Csaba Ringhofer
I saw some callstacks where table loading triggered by alter table events
dominated most threads. It turned out that the optimization in IMPALA-7320 is
not applied there and a file listing is initiated for each partition, even if a
single recursive listing could read all data.
