Benchmark request: badger v2 vs mongoDB

[tegk]

Could not find any benchmark.

How is the insert performance compared to MongoDB?

MongoDB and Dgraph are wildly different databases, so talking about "insert performance" is quite risky.
Are we inserting new relationships? new nodes? new pieces in a document? Those will have quite different performances on MongoDB.

Do you have some specific usecase for which we might be able to come up with a meaningful benchmark?

[tegk]

I am inserting a key value eg ("1", "test@test.com") and that couple million times.

Hey @tegk,

I just realized that this issue was under the badger repo and not the dgraph one.
This benchmark makes much more sense in that case hehe

We do not have this kind of benchmark at the moment but I do agree it would be an interesting one to perform.
I'll change the title of this issue and add it to our roadmap, although we could definitely use help with these, so if you're interested in contributing I'd love to assist you with it.

BTW, even before the benchmark we do suspect badger to be faster than mongoDB, as we've increased the performance of our writers substantially over the latest month or so.
A blog post will be coming up soon, but in the meantime you can check out @manishrjain's twitter thread on it here.

Thanks for the proposal!
