my7ym edited a comment on issue #1811: [CALCITE-3789] Support validation of 
UNNEST multiple array columns like Presto

   > We should also add a test case for at least one SqlToRelConverterTest.
   
   Will do it in the future if needed. I am still unclear that how this should 
be represented as RelNode. (discussed in 
https://issues.apache.org/jira/browse/CALCITE-3787)
   
    Is it OK for you?
   
   EDIT: Some other reasons:
   1. We still plan to communicate with Presto using SQL.
   2. RelNode -> SqlNode is not quite mature I believe, but I may be wrong 
there.
   3. The optimization enabled by RelNode is helpful. But not a high-pri since 
Presto will also optimize the internal execution plan.
