RangeScan or PrefixIterators and query options

[davedbase]

Hey, great work on this project so far!

I was wondering how or if PrefixIterators are supported in this binding yet? https://github.com/facebook/rocksdb/wiki/rocksdb-basics#prefix-iterators

I'm trying to implement a Hexastore with this binding and a range lookup based on the triple keys will be necessary.

As a side question do you plan on implementing any advanced querying facilities? I realize this is just a raw binding but here's to hoping :p

Hi @ddibiase - Thanks, it's been fun!

My plan is to eventually have full support for the RocksDB API. So far it's been relatively straightforward, and I haven't tackled any of the Rocks features which require user defined functions yet, i.e. Comparators, Filters, Merge Operators, and SliceTransform (required for prefix iterators).

On advanced querying, unless it's provided in the RocksDB API then no, I would see any extensions like that living in their own modules, which would be built on top of rocksdb-node.

In terms of 'roadmap', once I have the core RocksDB API reasonably supported (i.e. db.h et al) I plan moving on to some of the interesting features in the 'utilities', i.e. Backups, Date tiered DB, Geo DB, JSON Document, Spatial DB, etc.

Your hexastore sounds interesting!
