Unable to get EXPLAIN plan output

I am using datamaps and want to confirm whether queries are fired against it
or not -used following SQL

carbon.sql("EXPLAN select sum(x) from y group by A").show()
I have datamap created on table Y using the same above SQL.

Also, is there any way to use timeseries datamaps (with faster ingestion
time and less storage) and having level more than as I see it only supports
level 1 for minute,etc.?
