Summary of the MySQL Transaction Module Series

Module Summary

From January 3 to April 17, a 14‑article series was published that comprehensively introduces MySQL's transaction module.

The series includes:

01 – Initialization of the transaction pool and manager.

02 – Whether the BEGIN statement immediately starts a transaction.

03 – Allocation of a transaction object in memory.

04 – Preparation steps before starting a transaction.

05 – Variations of read, read‑only, and read‑write transactions.

06 – Temporary storage of binlog data before it is written to the binlog file.

07‑11 – Detailed walkthrough of the two‑phase commit process (prepare, commit, and its sub‑stages flush, sync, commit) and what InnoDB actually commits.

12‑13 – Creation of savepoints and rolling back to a savepoint, illustrating internal MySQL usage.

14 – Full transaction rollback.

The articles collectively explain the entire lifecycle of a transaction, from initialization to commit and rollback, including binlog handling and savepoint mechanisms.
