This was explored as part of discussion with zzzeek on various ways to make a statement with a large in_ be more performant. Batching the queries by chunking rp_ids did not help, but an expanding bindparam did: it makes the surrounding method about 50% faster [1]. bindparam expanding was added in sqlalchemy 1.2.0 so we bump the requirements here to the latest 1.2.x bugfix release, 1.2.19. [1] With the caveat that profiling and benchmarking are very different things, and in this case it is profiling results which are being analysed.
