[crucio]

We are for a few projects. We've been using them for over a year and have been impressed. We have 10s millions of items in there with lots of daily inserts/deletions etc. There's been a couple of gotchas but generally it is quite predictable and scalable.

We use 768 dimensional vectors for our items with several other payload filters (e.g. language). Performance has been good and I think the qdrant team focus on the right features without creeping into other areas.
