Summary of Changes
Hello @xzhangxian1008, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request enhances the TiFlash configuration documentation by providing a more detailed explanation of the cop_pool_size parameter. The update aims to give users a clearer understanding of how TiFlash manages and processes concurrent coprocessor requests, particularly when the configured pool size is surpassed, by introducing the concept of a rejection threshold.
Highlights
- Documentation Update: Clarified the behavior of the
cop_pool_sizeparameter in the TiFlash configuration documentation. The updated description now specifies that requests exceeding thecop_pool_sizewill queue if they are less than 10 times the specified value, and will be rejected if they exceed 10 times the specified value.
