Hi Steve, One thing useful to have for OGM would be a generalization of the hbm2ddl tooling so we can re-use it for managing NoSQL databases. Not all of them are "schemaless", e.g. Cassandra works with a fixed schema, and while MongoDB largely is schemaless, we still want to create stuff like indexes in the database.
I took a look and found that SchemaManagementTool as a pluggable service already goes halfway into that direction. The issue with it is that I cannot replace the list of exporters used by SchemaExport nor the list of tool targets used by SchemaUpdate. Having a pluggable service allowing me to customize that with an OGM-specific implementation should do the trick. As per some comments in the code, SchemaExport seems to be in some intermediary state, where the ops are not executed directly through the targets passed to SchemaCreator/Dropper but are read into String arrays which are then passed on to separate exporters. I suppose part of that work should be to consolidate this and basically follow the same approach as used in SchemaUpdate? Another facet is that for some OGM grid dialects we'd need another representation of commands than Strings, as not all the backends have a DDL but expect API invocations for that purpose. For that it'd be required to change Target#accept(String) into accept(Object) so we can pass some kind of command object. File exports would only work in a limited fashion, but we could live with that. Schema creation/dropping bound to the SF lifecycle is what I am after here. I'd be willing to work on this once we agree on the general approach. Any thoughts?
