Ok, so I took my first real look at the EntityStore APIs and I don't think you'd be able to shoehorn in Hibernate or another ORM like it easily. The best I can think of is if you dynamically generated a persistent entity class from the ComponentDescriptor and used that for persistence.
OTOH it would be fairly easy to fit the OfBiz Entity Engine in. But I also looked more at the IBatis store and that makes the most sense of all to me now if you're going to be storing to an RDBMS. Also, storing to something like HBase would be almost trivial or other BigTable, column-based, database. I kinda like that idea. One question I still have about the separation of the search and persistence is doing data aggregation and reporting. In one system I worked on trying to generate a report from a Lucene index with 10's of thousands of entries took several minutes. When I did a spike to see how long it would take to generate the same report from the data in a relational database using an SQL query, it took only a few seconds. I'm wondering what would be the best way of generating this type of aggregated, report type data in Qi4j. Rich Richard Wallace wrote: > Cool, sounds great.
