summary

Looks at pitfalls in MySQL XA (distributed) transaction processing that make it not crash-safe or fault-tolerant, and explains concrete analysis and fixes applied to MySQL 8.0 to make XA processing crash safe. Describes the engineering work and features added to MySQL 8.0 (building on prior MySQL 5.7 fixes used in Tencent TDSQL) so MySQL can reliably serve as storage nodes for a distributed DBMS such as Kunlun.
