Re: [I] Drill scan all the parquet file from query root for metadata if there is a "inner join " in query (drill)

   Hello,
   
   Is there any news on this issue? We have a similar issue on our side. As we add more parquet files in our data lake, the planning time increases due to Drill opening every single parquet under 'selectionRoot' even if `dir` columns are specified.
   
   NOTE: the problem seems to only appear with JOIN.
