In September 2020, I was honored to participate in the TiKV Linux Foundation’s (LFX) Mentorship Program. I worked on the Coprocessor support ENUM/SET project to help enable TiKV Coprocessor to support ENUM and SET calculations. This helped improve TiKV’s calculation performance. In this post, I’ll share with you some background information about my project, how I implemented the project, my lessons learned during community cooperation, and my future plans for this project.
