[GitHub] [shardingsphere] FlyingZC opened a new issue, #25674: [New Feature] Optimize transaction manager creation logic

["FlyingZC (via GitHub)" <gi...@apache.org>]

FlyingZC opened a new issue, #25674:
URL: https://github.com/apache/shardingsphere/issues/25674

   # Background
   Now all transaction managers on the classpath are created by default, which will cause some problems. 
   
   For example, when user only use local transactions, the atomikos xa transaction manager provided by ShardingSphere will be created by default. If the user does not have relevant permissions, an error will be reported.
   
   Related issues are as follows:
   1.Spring has created ShardingSphereConnection through the thread pool in advance.
   If you want to switch the transaction type, you cannot switch the transaction type corresponding to the currently created connection.
   https://github.com/apache/shardingsphere/issues/24694
   
   2.If there are both base and xa transaction dependencies in the class path, the creation of the xa transaction manager will fail.
   https://github.com/apache/shardingsphere/issues/23351
   
   3.Atomikos XA transaction started when it is not configured in server.yaml.

   # Tasks
   - [ ] Remove `TransactionTypeHolder` API.
   - [ ] Only create the transaction manager corresponding to the current `defaultType` transaction type
