At re:Invent 2017, Amazon Web Services (AWS) announced Amazon Time Sync Service which is a highly accurate and reliable time reference that is natively accessible from Amazon EC2 instances. It is much like the Google TrueTime which was published in 2012. Why do Google and AWS both want to make efforts to provide global time service? Is there any inspiration for building distributed database? This topic is important to think about.

Paxos or Raft is frequently used to ensure data consistency in the distributed computing area. But Paxos is known for its complexity and is rather difficult to understand while Raft is very simple. Therefore, a lot of emerging databases tend to use Raft as the consensus algorithm at its bottom layer. TiKV is no exception.

Every developer has his/her favorite programming language. For the TiKV team members, it's Rust.

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.

What happens when TiDB meets Jepsen?

The goal of TiKV is to support 100 TB+ of 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.
