With TiDB, BookMyShow has experienced increased uptime and availability, since TiDB automatically partitions and distributes data across the cluster. Meanwhile, operational and maintenance cost has been reduced by 30%. No engineer needs to be fully dedicated to database operations anymore. This post will introduce why BookMyShow chose TiDB over Greenplum by illustrating how TiDB solved their pain points.

Since PingCAP started building TiDB, it has encountered countless challenges, pitfalls, and critical design choices. Over the past three years, the PingCAP team has answered many questions from the users. Ed Huang, the CTO of PingCAP, has summarized these questions into “9 why’s” that every engineer may ask when looking at a distributed database and gives his answers to these questions in this post to help make decision-making of engineers a bit easier.
With our fast-growing business, the surging data volume posed a serious challenge to our backend system and put the operations team under great pressure. How to tackle these challenges became a thorny problem until we found TiDB, a MySQL compatible distributed hybrid transactional and analytical processing (HTAP) database, built and supported by PingCAP. Finally, we do not have to worry about scaling databases and can focus on building better applications for our users.
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.
The motivation behind building TiSpark was to enable real-time analytics on TiDB without the delay and challenges of ETL. Extract, transform, and load (ETL)--a process to extract data from operational databases, transform that data, then load it into a database designed to supporting analytics--has been one of the most complex, tedious, error-prone, and therefore disliked tasks for many data engineers. However, it was a necessary evil to make data useful, because there hasn’t been good solutions on the market to render ETL obsolete--until now.
With a fast-growing business comes soaring data size, which has placed tremendous pressure on Ele.me’s backend system, especially the database. How to tackle the challenges that come with mounting data has been a nightmare until we found TiDB, a MySQL compatible distributed hybrid transactional and analytical processing (HTAP) database, and its distributed key-value storage engine TiKV, both built and supported by PingCAP. Finally, we can harness the power of our data and not be intimidated by it.
In this 5-minute tutorial for beginners, we will show you how to spin up a standard TiDB cluster using Docker Compose on your local computer, so you can get a taste of its hybrid power, before using it for work or your own project in production.
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.
TiDB 2.0 is released! We absorbed insights and feedbacks from our customers, listened to requests and issues from our community, and reflected internally on our ultimate vision of building a distributed hybrid transactional and analytical processing database that scales itself, heals itself, and lives in the cloud.
As an open source distributed NewSQL Hybrid Transactional/Analytical Processing (HTAP) database, TiDB contains the most important asset of our customers--their data. One of the fundamental and foremost requirements of our system is to be fault-tolerant. But how do you ensure fault tolerance in a distributed database? This article covers the top fault injection tools and techniques in Chaos Engineering, as well as how to execute Chaos practices in TiDB.
Mobike has been using the TiDB database in the production environment since early 2017. Now they have deployed TiDB in multiple clusters with close to 100 nodes, handling dozens of TBs of data for different application scenarios. This post will provide a deep dive on why Mobike chose TiDB over MySQL and its sharding solutions by illustrating how TiDB solves their pain points.
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.
At the crack of dawn on February 1, I landed in Brussels, Belgium, for the first time in my life. The goal of my trip wasn’t to taste the local cuisine, tour world-famous museums, or grab a pint of the local brew. It was to deliver a talk three days later at FOSDEM 2018 Rust Devroom about our experience at PingCAP using Rust to build TiKV, a distributed transactional Key-Value storage engine.
On January 20th, 2018, more than 200 coders, hackers, and techies streamed into Garage Café, a chic coffee shop in the heart of Beijing’s techhub, Zhongguancun. They were there to be part of TiDB DevCon 2018, a technology party for the developers, by the developers!
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.

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.
