The goal of TiKV is to support 100 TB+ data and it is impossible for one Raft group to make it, we need to use multiple Raft groups, which is called Multi-raft.
TiKV uses the Raft algorithm to implement the strong consistency of data in a distributed environment. This blog introduces the details how Raft is implemented.
This article summarizes some best practices in using TiDB, mainly including SQL usage, OLAP/OLTP optimization techniques and especially TiDB's exclusive optimization switches.
This is the third one of three blogs to introduce TiDB internal.
