Hello Haomai, We are evaluating the key-value store backend which comes along with Firefly release (thanks for implementing it in Ceph), it is very promising for a couple of our use cases, after going through the related code change, I have a couple of questions which needs your help: 1. One observation is that, for object larger than 1KB, it will be striped to multiple chunks (k-v in the leveldb table), with one strip as 1KB size. Is there any particular reason we choose 1KB as the strip size (and I didn’t find a configuration to tune this value)? 2. This is properly a leveldb question, do we expect performance degradation as the leveldb instance keeps increasing (e.g. several TB)?
