For database products, point-in-time recovery (PITR) is a crucial capability. It allows users to restore their databases to specific points in time to protect against accidental damage or user errors. For example, if data is accidentally deleted or damaged, PITR can restore the database to its state before that time, thereby avoiding the loss of important data.
In this article, we’ll explore how PITR works with TiDB, an advanced, open-source, distributed SQL database. We’ll also discuss how we optimized PITR to maximize its stability and performance.
