Original topic: v6.1 Raft Engine 存储引擎 GA

Learning about the new features in V6.1, I found that the Raft Engine storage engine has reached GA. The official documentation describes it as follows:
Starting from v6.1.0, TiDB uses the Raft Engine by default as the log storage engine for TiKV. Compared to RocksDB, the new engine can reduce TiKV I/O write traffic by up to 40% and CPU usage by 10%.

In the PCTA v6 training Lesson 03, the TiKV-raft explanation still covers RocksDB Raft. Is there more information about Raft Engine? Besides GitHub.

The v6 courses are all based on 6.0.

TiKV uses SSDs, which are friendly for random writes. It seems that Raft Engine will have relatively greater benefits on non-SSD disks.
