[Question] _design/repl_filters

[fr2lancer]

Description

Hi. it actually is not a bug report.
I just wonder how _design/repl_filters is used.(as I can't find docs of this ).

I had to file copies from couchdb 2.x to couchdb 3.3.2 due to volume of data size. and started re-indexing(by grabbing all views under all_design doc) and I was able to see hips of size of doc under _design/repl_filters

1. What is used for? Is that a related to replication?
2. If yes, it can be reduced once replication is done?
3. Is that okay to delete it?

Thank you

Never heard of it. it's not part of couchdb.

thanks for the reply.

just I want to include this by googling it

https://lists.apache.org/api/plain?thread=dgfs5jyjt2v7zrqh4ctcg1o3pottw66h

there is 'old' source code which uses that rest api.
if it is not gonna used by any logic, I can happily delete it.

otherwise we need to consider about this.

Aha, thanks, that helps. I can confirm it was removed;

so it is safe to delete that design document now.
