ParadeDB is AGPL so not generally available on the hyperscalars. However, you can use https://github.com/timescale/pg_textsearch on Azure HorizonDB (and likely soon Flex). Disclosure: I'm the pg_textsearch maintainer and now at Azure.

I didn't quite follow your comment about vector support, are you asking for something beyond what pgvector + diskann provide (both available on Azure)?

ParadeDB maintainer here :). We would happily make it available on Azure (and all other cloud providers!) if there were a way for us to earn a living in doing so.

Fyi, we are in discussion with some hyperscalers on making this possible.

You dont support ultra-wide vectors from the largest embeddings models. We have to wierd stuff like chop up vectors across fields.

Some thing I've learned, but rarely seen explained anywhere: Storing the vectors is most likely not an issue, mostly likely you're having a problem with the indexes on top of them in which case you can use quantized vector indexes[0] (handled by pgvector) which will get past the limits imposed by PostgreSQL.

I had to switch off pgvecto.rs at some point and figured that out.

I don't have specific experience with the Azure environment here, but this probably applies if you have access to pgvector.
