Crate engine_rocks

Implementation of engine_traits for RocksDB

This is a work-in-progress attempt to abstract all the features needed by TiKV to persist its data.

The module structure here mirrors that in engine_traits where possible.

Because there are so many similarly named types across the TiKV codebase, and so much “import renaming”, this crate consistently explicitly names type that implement a trait as RocksTraitname, to avoid the need for import renaming and make it obvious what type any particular module is working with.

Please read the engine_trait crate docs before hacking.

RocksWriteBatch
RocksWriteBatchVec	RocksWriteBatchVec is for method multi_batch_write of RocksDB, which splits a large WriteBatch into many smaller ones and then any thread could help to deal with these small WriteBatch when it is calling AwaitState and wait to become leader of WriteGroup. multi_batch_write will perform much better than traditional pipelined_write when TiKV writes very large data into RocksDB. We will remove this feature when unordered_write of RocksDB becomes more stable and becomes compatible with Titan.
