Dikang Gu updated CASSANDRA-13475:
----------------------------------
    Status: Patch Available  (was: Open)

Here is the first version of the pluggable storage engine api, based on trunk. https://github.com/DikangGu/cassandra/commit/f1c69f688d05504f7409dd735e1473982c59fa52

It contains the API, and a little bit refactoring of the streaming part. 

You can check https://github.com/Instagram/cassandra/tree/rocks_3.0 for the RocksDB based
implementation.

> In order to support pluggable storage engine, we need to define a unified interface/API,
which can allow us to plug in different storage engines for different requirements. 
> In very high level, the storage engine interface should include APIs to:
> 1. Apply update into the engine.
> 2. Query data from the engine.
> 3. Stream data in/out to/from the engine.
> 4. Table operations, like create/drop/truncate a table, etc.
> 5. Various stats about the engine.
> I create this ticket to start the discussions about the interface.
