Subject [jira] [Commented] (CASSANDRA-2995) Making Storage Engine Pluggable
Date Tue, 23 Aug 2011 06:37:31 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2995?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13089296#comment-13089296

Stu Hood commented on CASSANDRA-2995:
-------------------------------------

bq. -1. "if you can't provide the same data model, you're creating fragmentation, not pluggability."
Anything that can implement ordered tables with compound keys can provide Cassandra's datamodel
(which is almost any disk-backed data store).

>             Project: Cassandra
>          Issue Type: New Feature
>          Components: Core
>    Affects Versions: 0.8.2

> Will you design and implement Cassandra's storage engine API like MyCassandra?
> MyCassandra provides extensible architecture for pluging other storage engines to Cassandra
like MySQL.  
> https://github.com/sunsuk7tp/MyCassandra/
>   
> It could be advantageous for Cassandra to make the storage engine pluggable.  This could
allow Cassandra to 
> - deal with potential use cases where maybe the current sstables are not the best fit
> - allow several types of internal storage formats (at the same time) optimized for different
data types
> - allow easier experiments and research on new storage formats (encourage research institutions
to do strange things with Cassandra)
> - there could also be potential advantages from better isolation of the data engine in
terms of less risk for data corruptions if other parts of Cassandra change
