> According to what we see in Hive source code, for transactional tables, the insert events are fired with a different API {{addWriteNotificationLog}}. Currently Impala fires {{firelistenerEvent}} for both transactional and non-transactional tables. We should look at what is the difference between the two APIs and see if we need to handle transactional tables differently.
