how many topics can handled by one node?

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?

[bytevigor]

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