Lsw_aka_laplace updated FLINK-21532:
------------------------------------
    Description: 
For now, both legacy Table/SQL API and implementation and current Table/SQL API 
and implementation are case sensitive when it comes to the key of table 
properties. Though it is highly recommended  to be full of low case, key in 
upper case still works well.

But the following case upon current code seems a little misleading..

Given a Ddl sql:

"""

 create table a (f string) with ('K1' = 'xxx')

""" 

The property of corresponding `CatalogTableImpl` is  Map(K1->xxx).

After calling CatalogTableImpl

 

 

 

> Make CatalogTableImpl#toProperties and CatalogTableImpl#fromProperties case 
> sensitive
