What is the unit of import in vector cache?

I’ve read about vector cache (Resource Planning | Weaviate - vector database). It seems to import a cache missed data into memory as long as we have available mem. But the doc does not mention what is the unit of read. Is it the entire vector index of the queried class, or shard, or part of shard?

Hi @roengram !

I believe the unit is a singular object. I have asked this question internally and will get back here when I get it from our team.
