Lessons from TiDB's No. 1 Bug Hunters Who've Found 400+ Bugs in Popular DBMSs
Lessons from TiDB's No. 1 Bug Hunters Who've Found 400+ Bugs in Popular DBMSs
Finding logic bugs is an important part of building a reliable Database Management System (DBMS). But sometimes the most obvious approach doesn’t work. You can’t just query several databases and compare the results. You need a more sophisticated bug-hunting approach. In this video, Manuel, a postdoctoral fellow at ETH Zurich, describes the techniques that have made him and his colleague, Professor Zhendong Su, TiDB’s #1 bug hunters. They’ve found over 50 TiDB bugs, and when you factor in their work with other popular DBMSs, they’ve found over 400.
