Basic concept Local Coordinator: In a distributed transaction, you must refer to the data on other nodes to complete the site of this part of your operation. Global Coordinator: The initiator of the distributed transaction, responsible for

Distributed transactions, like local transactions, contain atomicity (atomicity), consistency (consistency), isolation (isolation), and persistence (durability). Two-stage commit is an important method to ensure atomicity in distributed transaction.
