[GitHub] [shardingsphere] lite-up opened a new issue, #15420: App hanging when working with DruidDataSource

lite-up opened a new issue, #15420:
URL: https://github.com/apache/shardingsphere/issues/15420

   ## Bug Report
   
   ### Which version of ShardingSphere did you use?
   shardingsphere-jdbc-core-spring-boot-starter 5.0.0
   
   ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
   ShardingSphere-JDBC
   
   ### Expected behavior
   I'm currently using `DruidDataSource`, everything works fine. 
   
   ### Actual behavior
   However, if these below conditions being met: 
   1. `sharding-jdbc.max-connections-size-per-query > druid.maxActive`, 
   2. `Actual SQLs number > druid.maxActive`
   and then the application will be hanging forever for waiting for the next idle `Connection`;
   
   ### Reason analyze (If you can)
   1. `sharding-jdbc.max-connections-size-per-query > druid.maxActive`, 
   2. `Actual SQLs number > druid.maxActive`
   
   ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
   1. set `sharding-jdbc.max-connections-size-per-query > druid.maxActive`;
   2. and then simply do some `xxxMapper.selectList(null)` to make a ALL-SHARDING-TABLES-Scanning.
   
   ### Example codes for reproduce this issue (such as a github link).

   I think this is expected. `max-connections-size-per-query` should not greater than available in connection pool.
