Yep! Vector provides a lot of the same benefits, just as an OSS project. They were definitely a major inspiration. Vector's performance is similar to their published benchmarks. The biggest gap is (unsurprisingly) for larger (e.g. 100s of M - 1B+) datasets. We talk about it in the post, but the main improvement there is adding quantization to reduce the overhead of loading large posting lists. There's also a bunch of storage and caching layer work to be done. That's on our roadmap along with some cool features like full-text search and better support for multi-tenancy.
