There are lots of other differences. The default distributed storage engine of TiDB is TiKV, and TiKV is written is Rust. The transaction mode is different, and so on. The are something similar are they are both NewSQL, both use Raft to replicate data.

Thanks. swingbach.

The goal of TiDB is to create fault-tolerant distributed RDBMS. Especially for distributed transaction support. Let developers get benefits without changing any of their existing code.

Yes, currently TiDB works well with HBase. Coming soon. There are alse some distribute transaction layer on HBase.Ex:https://github.com/XiaoMi/themis

PostgreSQL support is on our roadmap.https://github.com/pingcap/tidb/blob/master/ROADMAP.md
