Before even looking into RocksDB we tried TokuMX and even got pretty well aquatinted with their dev team. We ran into the same issues when testing Wired Tiger. Neither could handle millions of mongo collections. Since we were involved in the RockDB storage engine from the beginning, we made sure the implementation could handle that many collections.

Yeah this reads like this person at Baqend is going over "lessons learned" while at Parse. That's why I thought it might be someone from Parse. It seems like bad form to write a blog post on what other people should have done differently and use that to publicize your own company. Parse was a success.

It's both lessons learned by Parse engineers and us, so I think the intended ambiguity is okay.
