ability to detect/find-out large streams

Hi, I’m wondering if there is some way to find out large streams (containing many events) in ES? e.g. using http api like $ce, $et system streams.
I guess projections could be used for such case, however maybe there are some hidden debugging tricks?

thanks,

Raimondas

can you define "find out large streams"? Is there some limit you are
looking for or?

well, I just would like to know if there is a stream containing more than N events in it.

My context is operational, since I have anomalies in our system where some streams are appended in an undesirable rate and I want to find out those streams.

You can either setup an $all subscriber that checks event numbers or
write a projection. I was just not sure how you wanted to configure
things.

Cheers,

Greg
