tristaZero opened a new issue #11048:
URL: https://github.com/apache/shardingsphere/issues/11048


   Hi,
   
   This issue is to add `ShardingSphereOptimizerTest` to assert whether 
`ShardingSphereOptimizer` can return the best physical executed plan.
   
   This class is a kernel process to do SQL optimization. #10889 and #11042 
make the optimizer levering ShardingSphere parser, but we need this test to 
confirm its basic function.
   
   ### Target
   Create `ShardingSphereOptimizerTest`  to test its `optimize()` function
   
   ###  Tips
   Create `TableMetaData` for `ShardingSphereMetaData` and utilize 
`OptimizeContextFactory` to create `OptimizeContext` for 
`ShardingSphereOptimizer`.
