Compared to BCC, the libbpf + BPF CO-RE solution greatly reduces storage space and runtime overhead. That's why we switched from bcc-tools to libbpf-tools. This post introduces some tips and tricks for writing BPF applications with libbpf.

This post dives deep into how transparent huge pages (THP) slow down the system. You'll learn why you should disable THP to improve your database performance and how to disable it in Linux.

Libbpf + BPF CO-RE is better than BCC. It greatly reduces storage space and runtime overhead, and it improves programmers' deployment and development experience.

Dr. Manuel Rigger and his colleague have found 400+ bugs in popular DBMSs, including 50+ TiDB bugs. Learn their experience in finding logic bugs in DBMSs.

Chaos Mesh is a cloud-native chaos testing platform that orchestrates chaos in Kubernetes environments. This article shares how to use chaos-mesh-action, a GitHub action to integrate Chaos Mesh into the CI process.

This post talks about why HTAP matters in a database platform, how TiDB implements HTAP, and how you can apply TiDB in different scenarios.

This post introduces in detail the features of TiDB Cloud - the fully managed, horizontally scaling, cloud-native, distributed SQL database in the cloud.

This article describes how we use TiPocket, an automated testing framework, to build a full Chaos Engineering testing loop for TiDB.

This post shows how to deploy a Hive cluster with TiDB to achieve horizontal scalability of Hive Metastore.

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.
