on paper https://github.com/yinqiwen/ardb does the same thing since 2013, and has other backends while defaulting to RocksDB.

Do you know what are the differences?

sorry for reply so late, I knew the ardb and it's a great project. the function of the kvrocks and ardb seems to be similar, but it's architecture and the design goal were totally different, so the performance also different.
