What is the max number of dimensions supported for a vector?

there is also the fact that the more dimensions you have for embedded data the more diluted the embedding becomes so it is unusual to go anywhere near the limits of vector length!

Earlier quoted context omitted.

my project deals w/ non-english text, bm25 performance is middeling. Language specific sparse model helps.

We will definitely look into it. The SPLADE models look promising!

why not surrealdb?

General consensus is it's really slow, I like the concept of surreal though. Our first, and extremely bare bones, version of the graph db was 1-2 orders of magnitude faster than surreal (we haven't run benchmarks against surreal recently, but I'll put them here when we're done)

Hey George, Alexander from SurrealDB here.

Congratulations on the launch! This is a very exciting space, and it's great to see your take on it.

Running fair benchmarks, not benchmarketing, is a significant effort and we recently put in this effort to make things as fair and transparent as possible across a range of databases.

You can see the results and links to our code in the write-up here: https://surrealdb.com/blog/beginning-our-benchmarking-journe...

We'd be very interested in seeing the benchmarks you'd run and how we compare :)

You can sacrifice many things for faster performance, such as security, consistency levels or referential integrity.

I'm genuinely curious to learn what design decisions you will make as you continue building the database. There are so many options, each with its pros and cons.

If you would like to have a chat where we can exchange ideas, happy to do that :)

This is very cool, and right up my alley. Hesitant to try it out because of the bespoke query language for now.

I wonder if you'd like to share your thoughts on GQL becoming an ISO standard? Also, have you looked into how Neptune Analytics handles vector embeddings?

> In-house graph-vector storage engine (to replace LMDB) Not sure if it's possible. But why not use fjall, if it is? [0] [0]: https://github.com/fjall-rs/fjall/

We went with LMDB because it was a lot faster. But will definitely look over this before we work on our own engine
