---------------------------------------
Summary: Skip events happen before manual REFRESH
Key: IMPALA-11535
URL: https://issues.apache.org/jira/browse/IMPALA-11535
Project: IMPALA
Issue Type: Improvement
Reporter: Quanlong Huang
If the table has been manually refreshed, all its events happen before the
manual REFRESH can be skipped.
This happens when catalogd is lagging behind in processing events. When
processing an event, we can check whether there are manual REFRESH executed
after its eventTime. In such case, we don't need to process the event to
refresh anything. This helps catalogd to catch up HMS events quickly.
