Subject [jira] [Commented] (OPENJPA-1744) Support JDO
Date Thu, 31 Mar 2011 21:45:05 GMT


Michael Dick commented on OPENJPA-1744:

Most of the nonrelational support is still in place - a rudimentary xml store was part of
the initial code drop and is (afaik) still usable.

Implementing a different spec on top of the OpenJPA kernel would be a significant undertaking.
Is there anything specific to JDO that makes it more (or less) usable with non relational
stores? I'm looking for pros and cons of adding JDO over implementing a hadoop / big table
store that uses JPA interfaces?

 This request is to bring compliance with the latest JDO specification back to the implementation
so that it can be used with nonrelational backends like Google BigTable, Hadoop, etc.
