> ALTER_TABLE event could trigger full refresh on the table, which is expansive
> and can lead to event-processor lagging behind. We need logs to show the
> difference between the before and after hmsTables so we can further
> distinguish the cases that actully don't need a full table refresh. E.g.
> altering the owner don't need to reload the file metadata.
