[Refactoring] New architecture of runtime context for Sharding
Proxy and JDBC
Hi fellows,
There is a significant change for release 5.x need to be public to our community.
To get a consistent and straightforward orchestration function for both of Sharding Proxy and Sharding JDBC,
we extracted the joint members from them, which will be passed down to `shardingsphere-underlying` module. Based on that, orchestration engine could function simply and uniformly.
A todo list is appended here.
-[ ] Remove cache from Sharding Parser
-[ ] Call the `clear()` of Sharding Parser when needed
-[ ] Exact joint members from Sharding Proxy and JDBC to group into a new new `SchemaContext`
-[ ] Pass a list of `SchemaContext` named `SchemaContexts` to `shardingsphere-underlying`
-[ ] Refactor the behaviors of `orchestration`
Since pictures can not show well in dev list,
you can learn the view of the new structure and relationships of related classes from [1].

This is a good idea. We can create a new module to process them.
I just send a new thread[1] to talk about the new module.
