Why BIGO Chose an HTAP Database over MySQL for Horizontal Scaling and Complex Queries — The creators of TiDB (an open-source, MySQL-compatible, horizontally scalable database) seem to be on a roll with these case studies, but unlike many business-oriented case studies they touch on a few interesting technical details.

Why Japan's Largest Mobile Payment Company Migrated from Aurora to TiDB — This is a case study hosted on TiDB’s own site, so apply a cynical eye, but the story is interesting nonetheless and the company in question found bottlenecks with Aurora that were resolved by TiDB’s horizontal scalability. PingCAP has also just released version 4.0 of TiDB.

How TiDB's HTAP Makes Truly Hybrid Workloads Possible — This post introduces the design details of the HTAP architecture of TiDB, including the real-time updatable columnar engine, the multi-Raft replication strategy, and smart selection.

TiDB 4.0 Released: A Hybrid, Open Source HTAP Database — TiDB is an elastic, real-time Hybrid Transactional/Analytical Processing (HTAP) database built in Go(lang) that can act like a traditional relational database, a NoSQL database, or an analytical database all out of one box.

TiDB 4.0: A Peek into the Future of Databases? — Everyone who’s building a database system thinks their approach is the future and PingCAP are no different proclaiming their TiDB 4.0 release candidate as “the prototype of what the future database looks like.” The core idea is that databases will continue to get more ‘intelligent’ in scaling, scheduling and adapting to unpredictable workloads.

Choosing the Right Databases for Shopee's Applications — It’s worth noting this article is hosted by PingCAP, creators of TiDB, but beyond that it’s a look at the process of choosing which databases best suit your use cases by two engineers at a large Asian e-commerce platform (Shopee). Unsurprisingly, TiDB features heavily here, but also Redis and MySQL.

Why a Game Company Chose a Distributed SQL Database Alongside MySQL — Yes, this is a TiDB case study, but it’s interesting to see why a company chose it over other MySQL-based and NewSQL storage solutions.

TiDB in the Browser: Running a Go-Based Database on WebAssembly — An interesting demo. If a database like TiDB written in Go can run in the browser, what about other complex Go apps or other database systems? SQLite is another database that is easily compiled to WebAssembly.

Lesson Learned from Queries over 1.3 Trillion Rows of Data Within Milliseconds — No big releases, so we’re leading with a detailed, technical case study this week 😄 Zhihu is China’s largest question and answer site (think Quora) with over 220 million users. This post digs into how they use TiDB to keep things running at a low latency at scale.
