    Insightful video. Have been trying to delete and write to an indexed column in the same transaction and running into deadlocks. Was thinking my WHERE clauses would prevent issues before learning more about index locks

    This is very interesting-I came across a video introducing my blog post. Actually, the official MySQL B-tree implementation hasn’t been updated in a long time. In fact, the next post in my blog series discusses how, in PolarDB, we have modified MySQL’s B-tree to a structure similar to PostgreSQL’s Blink-tree. Additionally, there is a third article in the series, which builds upon this topic. Here’s a Chinese blog post explaining the implementation of PolarDB’s Blink-tree. Unfortunately, I haven’t had the time to translate it into English yet.

    Thanks @hnasr, read the original blog as well. Great read.
    Lecture from andy's course at CMU might be helpful, if someone wants to get more context on how concurrency is handled in B-Trees: ua-cam.com/video/lgUNTj0Q54M/v-deo.html

    Can a deadlock happen? If a reader is coming from top to bottom; while there was a SMO downthere by a writer then the writer is trying to acquire X lock on parent node acquired by that reader?
