[Bug] [metadata] DriverPool key needs to include a type to distinguish the JDBC connector types. #4514
Description
Search before asking
- I had searched in the issues and found no similar issues.
What happened
两个MySQLCDC任务，先后同步到mysql和postgres，postgres的sink会复用mysql的driver，造成混淆。看代码是org.dinky.metadata.driver.Driver#build方法获取缓存的键值问题。键值为connector，未考虑到connector为jdbc时可能有多种（MySQL、postgres等），因此需要增加缓存维度。计划提交PR
What you expected to happen
两个MySQLCDC任务，先后同步到mysql和postgres，二者互不影响
