>
> 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.
