GoLevelKV

An embeddable key-value store built on top of goleveldb to provide compare-and-swap operations and key-based transactions!

Description

This is just a wrapper around goleveldb to provide atomic per-key transactions! This works by just bucketing all the requests into a finite number of goroutines, and having each goroutine process requests for a certain subset of the key range. This forces per-key serialization on top of the database, letting us have transactions.

TODOS

• Use a better system than bucketing, like lockless per-key queues to improve scalability (and awesomeness)
• Extend the API a little bit possibly
• 100% test coverage
• Benchmark performance
• Build a Raft-distributed layer on top of this (will be in a different repository)
• Allow for more sophisticated operations (serializable transactions covering several keys)
