@msokolov I wasn't sure about attempting to index a large amount of vector
data, given that it'll take up a few GB of RAM. I've added a test for now,
please let me know if I should keep it (or how to test it better). Perhaps
having the test is fine, because we run Faiss tests (and only those) in a
separate GH action?
The test fails reproducibly when added to `main`:
```

ByteBuffer. Size: 2149576700
