Single Alert message for the batch/stream

I have Tickscript with batch node. InfluxQl, I am using contains a group by clause with time and other tag.

so for every tag combination, a lambda expression with `crit` is processed and appropriate action is taken. This creates huge number of messages(or mails, apparently for every tag combination in GROUP BY clause).

Is there any way to send a consolidated message with all the alerts merged to one single message?

Start by examining how batch and stream nodes process GROUP BY tag combinations and how alert actions emit notifications. Determine the scope of consolidating alerts into one message and what notification behavior should count as done.
