I used to create drill file programatically, but how we can promote a folder which contains parquet files programatically?
Programatically as in, by use of scala programs.
Basically Drill file used to be like
View Name: ABC
Command: Select * from HDFS Location
Here in above view, command contains HDFS Location , which is a location where parquet files are present.
The option you suggested will create/export the data in another file format, which will be copying the data from one formate to another,which is memory consuming process.
