> We want the {{NOTIFICATION_LOG}} table to capture additional information about the metadata
objects when {{DbNotificationListener}} captures different events for a table (create/drop/alter)
and a partition (create/alter/drop). We'll use the messages field to add json objects for
table and partitions for create and alter events. The drop events message remains unchanged.
These messages can then be used to replay these events on the destination in event of a replication,
in a way that will put the destination in a state that's consistent with one of the past states
of the source.
