> As part of HIVE-9174, a new notification listener, DbNotificationListener was introduced that stores notification messages in the metastore.
> Now, the "message" field of a Notification event can be arbitrarily long, since it is a JSON-serialized message of what event actually occurred, and an AddPartitionMessage which captured the result of an add_partitions can be arbitrarily long (as long as the number of partitions that were added).
> However, the "message" field for the storage in db is limited to VARCHAR(1024), which it will easily break. We need to fix this somehow.
