Is it a bad idea to use periods within a consumer group name? "my-service.topic1_consumer_group"
I vaguely remember reading somewhere that it's a bad idea to use periods
within Kafka consumer group names because it can potentially conflict with
metric names.
I've searched, and not finding anything, so am I just mis-remembering?
It is operationally convenient because zookeeper CLI allows tab completion
within periods.

Thanks Praveen.
I realized I'd been mis-remembering the warning that I'd been seeing. The
limitation is for topic names, not consumer group names:
*WARNING: Due to limitations in metric names, topics with a period ('.') or
underscore ('_') could collide. To avoid issues it is best to use either,
but not both.*

Not that I know of. We at Flurry have been using periods in our group names
for a while now and haven't encountered any issues b/c of that.
