描述

**描述你使用过程中遇到的问题: ** Hello I want to ask, when I connect to mycat to perform a transaction, using the read-write separation function, the back-end cluster to switch, if I am a write operation, the subsequent execution is still in the transaction ?

研究方向
The issue asks whether a write operation within a transaction will remain in the same transaction when the read write splitting switches backend clusters. Research Mycat's transaction handling and read write splitting logic. Check the Mycat documentation or source code (e.g., `MycatServer.java`, `TransactionManager.java`) to determine how transaction boundaries are maintained across backend switches. Provide a clear answer with references.
