TiDB 1.1 Alpha is now released!
Thank you all, our beloved contributors, customers, and partners, for an amazing 2017! Hello, 2018!
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.
PingCAP, a cutting-edge distributed Hybrid Transactional/Analytical Processing (HTAP) database company, is excited to announce the opening of its Silicon Valley office, located at the GSV Labs in Redwood City, California.
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.
TiDB is compatible with MySQL, strong consistent and highly available.

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.
TiDB Pre-GA is now released! This release is focused on MySQL compatibility, SQL optimization, stability, and performance.
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.
This document is a use case details the reasons why yuanfudao.com chose TiDB as its backend database solution to tackle their fast data growth and complex queries.
TiDB RC4 is now released! This release is focused on MySQL compatibility, SQL optimization, stability, and performance.
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.

In order to accelerate expression evaluation, we recently refactored its framework. This tutorial will show you how to use the new computational framework to rewrite or add a built-in function in TiDB.
TiDB RC3 is now released! This release is focused on MySQL compatibility, SQL optimization, stability, and performance.
This is the speech Siddon Tang gave at the 1st Rust Meetup in Beijing on April 16, 2017.
This is the speech Edward Huang gave at Percona Live Open Source Database Conference 2017.
This document is a use case that details the performance of MySQL and TiDB with tens of millions of rows of data per day.
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.
This document describes how to add built-in functions to 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.
This document gives an overview of MVCC implementation in TiKV.
