Migrating the TiKV Rust Client from Futures 0.1 to 0.3
This post introduces Nick's experience in migrating the TiKV Rust client from Futures 0.1 to 0.3.
Titan: A RocksDB Plugin to Reduce Write Amplification
As a RocksDB plugin for key-value separation, inspired by WiscKey, Titan is available for preview in TiDB 3.0. This post introduces the design and implementation of Titan.
How TiKV Uses “Lease Read” to Guarantee High Performances, Strong Consistency and Linearizability
This post discusses Raft Log Read, `ReadIndex` Read, and Lease Read, and why TiKV adopts the Lease Read approach.
Landing Your First Rust Pull Request in TiKV
This guide is intended to show how you can land your first Pull Request (PR) in Rust to contribute to TiKV in less than 30 minutes. But before we do that, here's some helpful background.
Implement Raft in Rust
As an open-source distributed scalable HTAP database, TiDB uses the Raft Consensus Algorithm in its distributed transactional key-value storage engine, TiKV, to ensure data consistency, auto-failover, and fault tolerance. TiDB has thus far been used by more than 200 companies in their production environments in a wide range of industries, from e-commerce and food delivery, to fintech, media, gaming, and travel.
How to Do Performance Tuning on TiDB, a Distributed NewSQL Database
Doing performance tuning on distributed systems is no joking matter. It's much more complicated than on a single node server, and bottlenecks can pop up anywhere, from system resources in a single node or subcomponent, to cooperation between nodes, to even network bandwidth. Performance tuning is a practice that aims to find these bottlenecks and address them, in order to reveal more bottlenecks and address them as well, until the system reaches an optimal performance level. In this article, I will share some best practices on how to tune "write" operations in TiDB to achieve maximum performance.
A TiKV Source Code Walkthrough – Raft Optimization
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.
Why did we choose Rust over Golang or C/C++ to develop TiKV?
Every developer has his/her favorite programming language. For the TiKV team members, it's Rust.

The Design and Implementation of Multi-raft
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.
A TiKV Source Code Walkthrough – Raft in TiKV
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.
