When TiDB Meets Jepsen

What happens when TiDB meets Jepsen?

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.

TiDB Internal (III) – Scheduling

This is the third one of three blogs to introduce TiDB internal.

TiDB Internal (I) – Data Storage

This is the first one of three blogs to introduce TiDB internal.

TiDB Internal (II) – Computing

This is the second one of three blogs to introduce TiDB internal.

Rust in TiKV

This is the speech Siddon Tang gave at the 1st Rust Meetup in Beijing on April 16, 2017.

About the TiDB Source Code

The target audience of this document is the contributors in the TiDB community. The document aims to help them understand the TiDB project. It covers the system architecture, the code structure, and the execution process.

Subquery Optimization in TiDB

Subquery optimization, especially rewriting the correlated subquery, is a very difficult part in SQL query optimization. To be compatible with MySQL, TiDB enables users to write subqueries anywhere they want. For those subqueries that are not correlated, which are also called uncorrelated subqueries, TiDB evaluates in advance; for those correlated subqueries, TiDB removes the correlations as much as possible. For example, TiDB can rewrite a correlated subquery to `SemiJoin`. This article is focused on introducing the correlated subquery optimization methods in TiDB.

MVCC in TiKV

This document gives an overview of MVCC implementation in TiKV.

A Deep Dive into TiKV

This document introduces how TiKV works as a Key-Value database.
