Does it require core patches or I can install it into the standard upstream Postgres? Asking because, afaik, it did, but it might that something has changed already.
It still requires some patches to the Table Access Method API which have been submitted upstream:
Additionally, OrioleDB beta12 features a new fastpath tree search, which can accelerate workloads with intensive key-value lookups by up to 20%. Stay tuned for a new blog post about this later this week.
Awesome. How far away would you say are you from a stable orioledb as postgres extension?
Great work!!
