Why was HaloDB not considered?

I had a quick question regarding the purpose of StormDB:

• Was HaloDB not sufficient for your use case?
• How does StormDB compare against HaloDB? I think, both StormDB & HaloDB have similar purposes ie both seem to be log-structured KV-store written in Java for fast point lookup and iteration.

PS: The codebase is clean and simple. Great job!

Hey @arjunsk, HaloDB was considered in the internal tests, and due to poor performance, we removed it out of the comparison.

Also, StormDB isn't a log structured KV store.

Hey @judepereira,

Thanks for the response.

I am having some follow-up questions,

• What was the project use case for building StormDB? (I read the motivation statement which talked about sequential reads, but where was the sequential read important?)
• Is it used inside CleverTap mobile SDK? Or at the server side? (I couldn't find any CleaverTap OSS project which used StormDB)

Looking forward to your reply!
