AI-generated summary

The overall system consists of a distributed transaction with two transactions, and System A is the initiator of this distributed transaction. The system can complete distributed transactions to some extent through both MQ distributed transactions and remote calls. However, MQ distributed transactions are needed because they are executed asynchronously and have a higher throughput.

The overall system is shown below:

There is currently a distributed transaction (i.e., transaction 1 and transaction 2), and System A is the initiator of this distributed transaction.

For MQ distributed transactions
For remote invocation

By comparing the two methods mentioned above, it can be observed that both can achieve distributed transactions to some extent. So why do we still need MQ distributed transactions? This is because MQ distributed transactions are executed asynchronously and have a higher throughput.
