Subject [jira] Commented: (NUTCH-811) Develop an ORM framework
Date Tue, 13 Apr 2010 18:44:55 GMT


Enis Soztutar commented on NUTCH-811:

Actually, we plan to develop the code for this layer in another project because, 
 - ORM layer is orthogonal to Nutch code, so it does not belong there
 - Extracting the code will be much harder later
 - If developed well, this code will be useful to other projects (interesting is that there
is no API to support both HBase and Cassandra)
 - Code will be much more clean 
 - Nutch can use the artifacts from this project

Nevertheless, we plan to piggyback on the Nutch community to support the initial development,
review and exposure. I will update this issue as the code develops, and will kindly ask for
reviews. In the long term, we can move the project to Apache Sandbox, or as a Hadoop/Nutch
sub project (once Nutch becomes TLP). 

A design document and initial code will be available shortly.

> By Nutch-808, it is clear that we need an ORM layer on top of the datastore, so that
different backends can be used to store data. 
> This issue will track the development of the ORM layer. Initially full support for HBase
is planned, with RDBM, Hadoop MapFile and Cassandra support scheduled for later.
