Query Type: SQL | PHYSICAL | LOGICAL

Hi,

On the Drill GUI Query page, there is radio button named "Query Type"  with
3 options SQL | PHYSICAL | LOGICAL

Any idea what  PHYSICAL | LOGICAL mean here?

Regards

SQL one means the SQL language. Usually, we use this one.

Logical, physical plans are plans (think of it as scripts) for drill engine to run. They are usually generated by machine, so they are used mainly for development/experiment purpose.
