[hibernate-dev] [OGM] Polyglot module: wdyt ?

Hello everyone, Following a discussion I had with a colleague of mine about polyglot persisting, I was wondering if it could be possible to store entities into one datastore and associations into another one. Let's take an example: I'm developing an application like a social network, it can be interesting to suggest new relations so a graph database is an interesting choice (to store people relations) but profiles information can easily be stored into a document store. It can really be tough to manage the consistency between both datastores. So here comes the polyglot module idea. We already have methods for entities and methods for associations we just need to delegate calls either to the dialect responsible for the entities or the dialect responsible for the associations. Starting from here I had 2 choices: - create a module and some specific submodules to enable polyglot capabilities - create a module and invoke the existing modules (Infinispan, Ehcache and MongoDB), manage the lifecycle of their datastore provider and dialect and then delegate the appropriate calls I choose the second option because it would a significant amount of work to recreate new dialects (for " polyglot" mongodb, infinispan and ehcache) and maintain the "classic" module and their "polyglot" siblings. I have test the new module with all 6 combinations and all tests are passing, the documentation has been updated and a branch is available on my github repo [1]. So now I'm coming to you with a simple question: WDYT ? Cheers, Guillaume [1] https://github.com/gscheibel/hibernate-ogm/tree/polyglot
