Limit for number of channels?


The docs indicate that channels are very lightweight, however I’m curious as to the scalability of channels in general. Can a sync gateway handle thousands of channels? How about hundreds of thousands?

What is considered an “extreme” number of channels and does horizontal scaling of the sync gateway scale the number of channels that can be used?


The total number of channels matters less than the average # of channels per document. If every document is in dozens of channels that will be more expensive than each document being in only a few.

We have an application where in each user has some specific appointment data. They do not cross over. So if we have 1000 users, can there be 1000 channels? Will there be a performance impact?

Thank you!
