State of RocksDB

1

What is the state of RocksDB for Rust?

It seems to me there are three versions:

  1. https://github.com/spacejam/rust-rocksdb
  2. Parity fork of 1, https://github.com/paritytech/rust-rocksdb
  3. PingCAP fork of 1, https://github.com/pingcap/rust-rocksdb

What are the changes and why are they forked?

Now the main repository is under organization, https://github.com/rust-rocksdb/rust-rocksdb, but Parity/PingCAP forks still exist and I am still mystified. Does anyone know?
