Subject [jira] [Commented] (CASSANDRA-2995) Making Storage Engine Pluggable
Date Tue, 23 Aug 2011 17:06:29 GMT


Jonathan Ellis commented on CASSANDRA-2995:

I understand the "wouldn't it be cool" factor but let's be clear: Cassandra is not a research-paper
creation engine.  Pluggability here improves generality at the cost of a substantial increase
of implementation complexity, QA work, and cognitive burden on users.  This is a bad direction
for the project.

>                 Key: CASSANDRA-2995
>                 URL:
>             Project: Cassandra
>          Issue Type: New Feature
>          Components: Core
>    Affects Versions: 0.8.2
>            Reporter: Muga Nishizawa
> 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.  
> 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
