This is the speech Siddon Tang gave at Bay Area Rust Meetup August 2017.
Data was corrupted. A cluster panicked. The crime scene was compromised. What happened? Detective Huang went all lengths to locate the criminal and solved it once and for all.
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 is the first one of three blogs to introduce TiDB internal.
