I believe the 1024 limit has been upped in recent versions of Elasticsearch

https://github.com/elastic/elasticsearch/issues/92458

Elasticsearch is written in Java and its source code is available on Github.

I don't think the murmur3 hash implementation has changed since it was added as the default in version 2.0 (see the [changes](https://github.com/elastic/elasticsearch/commits/main/server/src/main/java/org/elasticsearch/cluster/routing/Murmur3HashFunction.java)). The plugin itself has seen [more changes](https://github.com/elastic/elasticsearch/commits/main/plugins/mapper-murmur3) but that's IMO because of internals and not visible changes in the calculations.

Mysql is not as open source as postgres (long story). And you can see how open elasticsearch is by just having access to the bugs database https://github.com/elastic/elasticsearch/issue

In this tutorial, I introduce Weaviate, an open-source vector database, with the thenlper/gte-base embedding model from Alibaba, through Hugging Face's transformers library.

This will be solved in Weaviate https://github.com/weaviate/weaviate/issues/2424

Hey @rvrs, I work on Weaviate and we are doing some improvements around increasing write throughput:

1. gRPC. Using gRPC to write vectors has had a really nice performance boost. It is released in Weaviate core but here is still some work on do on the clients. Feel free to get in contact if you would like to try it out.

2. Parameter tuning. lowering `efConstruction` can speed up imports.

3. We are also working on async indexing https://github.com/weaviate/weaviate/issues/3463 which will further speed things up.

In comparison with pgvector, Weaviate has more flexible query options such as hybrid search and quantization to save memory on larger datasets.
