Remark42 cluster version

[StarAurryon]

Hello there,

Just to announce that I have implemented a cluster backend for remark42 to use mongodb / s3 for image and engine store.

https://github.com/Fenritec/remark42-cluster

The implementation is complete for the image store and 80% for the engine store. So main functions are working and I need to write the tests to make it complete.

Feel free to give feedback.

The project is released under EUPL v1.2.

nice.

I have moved it to discussions as this is not really a bug report

@umputun I have just one question. I saw that some query limit are hard-coded into the bolt engine backend. Shouldn't it be better to have standard behavior across all backends by having a common logic ?

[umputun]

I'm not sure what limits you mean exactly, but my guess would be

const (
	// limits
	lastLimit = 1000
	userLimit = 500
)

Probably making it some struct and passing to the engine will be a good idea. Obviously, this way it can be also configured

I'm interested in your PR as well, and please let us know if in some place you would expect to see RPC storage support but didn't find it.

[StarAurryon]

What are you calling "RPC storage" ? RPC is already implemented for engine and image. Is it for the avatars?

[paskal]

You are right, all four of data, admin, image, and avatar storage support rpc, I've overlooked it looking at the documentation for some reason.

[paskal]

Actually after careful re-check I was wrong twice: first image storage has RPC storage but it was not mentioned in the parameters documentation (fixed in #1358), but second - avatar storage missing RPC store support and example implementation. I propose to create an issue about it if you'll need it.

[StarAurryon]

For our project it is not needed as the avatar lib you rely on has a mongo storage backend. But we can definitely make a RPC backend in the future.
