it depends on your use case and hardware, there is no hard limit, you need to test and adjust.

thank you for your response. i want to use it for user notification, one topic per user, which means about 100,000 topics to create, i will test for it.

one topic per user is not a suitable scenario to use luxun, physically, one topic needs a file with 128M as minimum size, I think you need to partition your users to reduce topic.

ok, i got it. any suggest to partition users?

Answer 5 · 2014-02-28T02:39:52.000Z

depends on your use case, partition by user region, or some kind of hashing.
