Subject [jira] [Commented] (CASSANDRA-13475) First version of pluggable storage engine API.
Date Tue, 31 Oct 2017 18:28:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13475?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16227275#comment-16227275

Aleksey Yeschenko commented on CASSANDRA-13475:
-----------------------------------------------

bq. So next step, I will try to abstract the keyspace and CFS classes, as you suggested, and
have a list of steps of how I will refactor existing engine

I'd suggest starting with a plan first, before you invest too much work into coding it up,
so that you don't waste any time in case there is disagreement regarding the roadmap (though
some code changes just for exploration/discovery/illustration could help too).

> 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.
