   Maybe this issue is well for me: How to transform the parsed result of ShardingSphere to the algebra of Calcite.
   I have done some work a few months ago, and I'm familiar with the ast of ShardingSphere parsed result. 
   Also, I am investigating the query optimization module of calcite, but until now, I think there is still a long way to go.
