Subject [jira] [Commented] (CASSANDRA-13475) First version of pluggable storage engine API.
Date Thu, 19 Oct 2017 23:34:01 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13475?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16211918#comment-16211918

Dikang Gu commented on CASSANDRA-13475:
---------------------------------------

Also, the Partition interface (https://github.com/Instagram/cassandra/blob/rocks_3.0/src/java/org/apache/cassandra/db/partitions/Partition.java)
could be part of the storage engine interface, we implemented a RocksDBPartition under that,
and it works very well with other iterators in C*.

> 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.
