I think that network and storage access in distributed transaction execution processes need burying points:

Transaction main stream：

1. start Transaction(Client->Server): DefaultGlobalTransaction.begin
2. registry branch(Client->Server): AbstractResourceManager.branchRegister
3. report branch(Client->Server): AbstractResourceManager.branchReport
4. Transaction commit(Client->Server): DefaultGlobalTransaction.commit
5. Transaction rollback(Client->Server) : DefaultGlobalTransaction.rollback
6. branch commit(Server->Client): DefaultCoordinator.branchCommit
7. branch rollback(Server->Client): DefaultCoordinator.branchRollback

Other stream:

8.is lockable check(Client->Server): DataSourceManager.lockQuery
9. store access of file: FileTransactionStoreManager (incude read & write)
10. store access of database: LogStoreDataBaseDAO (incude read & write)
