Hi devs,

I did some investigation on data source v2 feature and have some questions:

  1.  View is not supported for now, eg, CREATE VIEW,  this feature is not 
finished or datasource v2 won’t support view?
  2.  Column resolution are failed when use datasource v2, eg,

select tbl.col from tbl   will failed with cannot resolve '`tbl.col`' given 
input columns

select col from tbl  is ok

  1.  For “describe table”, when implement the datasource V2 table,  we can set 
the user properties and get it according to the interface in Table: Map<String, 
String> properties(). But for some properties, eg,  “Create time”, “Create by”, 
they are not user properties, should we also put them in properties?
  2.  Is there a plan for datasource v2 and I’m interested in take some related 
tasks.



Best regards,
Colin Ma
