---------------------------------------
Summary: Add metrics for CatalogdTableInvalidator
Key: IMPALA-14684
URL: https://issues.apache.org/jira/browse/IMPALA-14684
Project: IMPALA
Issue Type: New Feature
Components: Catalog
Reporter: Quanlong Huang
We need catalogd metrics to show how many tables are invalidated due to TTL and
memory pressure. Also add metrics to show the rate of them, e.g. numbers in the
past 1s/1m/5m/30m, etc.
These help admins to adjust configurations like invalidate_tables_timeout_s and
the JVM heap size of catalogd.
