Hi, sorry Andy, a lot of things have been going on here. We switched back to TDB again (at least my code is generic enough now to be easy to switch back and forth).
We keep having a problem with growing databases, both in SDB and TDB, both recent snapshots (pre-2.10 release). Our typical use case is that we fetch triples from sources and store it in a named graph with ID equal to the source URL. We delete the old data before we do. I wonder if this is a typical use case or that people normally keep their triples forever and never overwrite. We do use layout2, but I can't recall if it was hashed or indexed at this moment (I'm home now). I would love to contribute to Jena, but it would cost me some effort to dive into it, get up to speed and trace the problem. A problem is that the project will come to an end for me soon, but a team member might take over. I will keep it in mind. The least I can do is add a failing unit test that points out the problem. Not sure if that will be possible (or even desirable) in the two-week window you set for the upcoming release. You will hear from me when I have anything to contribute. Thanks for now and have a nice weekend!
