Can v2.0.1 work well with rocksdb 0.15.0?

[ws4charlie]

Hi, I am sorry to bother you guys and put my question in here which might not be the correct place. I have been looking for a Merkleized KV store for my project and this Merk looks pretty nice to me. After looking into the latest release 'v2.0.1' for a while, I noticed that the Merk is still using rocksdb 0.14.0 instead of 0.15.0, which is now being used in develop branch of Merk.

The question is that can I simply point underlying rocksdb to 0.15.0 on a fork of Merk "v2.0.1" and assume that everything will be working fine if "cargo test" pass? The reason I wanted to upgrade to rocksdb 0.15.0 was that it provides both upper_bound and lower_bound options for iterator. I appreciate it if any of you guys could help me on this. Thanks a lot.

Hey @ws4charlie, thanks for your interest in merk!

As far as I know, updating to 0.15.0 shouldn't cause any issues. I'll be creating a new merk release soon including the recent work on chunk proofs and queries which will include 0.15.0. Then if you'd like to submit a PR using the upper/lower bounds that would be very much appreciated (could be rust-idiomatic, e.g. fn <R: RangeBounds<&[u8]>>range(&self, bounds: R) -> MerkIter { ... }).

Sure. I'll do it but just by simply exposing an iterator accepting customized options. I'll let you know.

Hi @mappum , Seems I can't push branch or create PR on Merk. Could you please check and see my revised source file mod.rs(test cases included) for range-based queries. Can you please let me know your decision for the release? Thanks a lot.

@mappum Hi, when will the new version be released？
