Hello
I have load (as CTAS) into parquet-files StarShema Benchmark generated
csv-data (scale factor 50)
For one of bencmark query's like :
select
d.d_year,
c.c_region,
sum(l.lo_extendedprice*l.lo_discount) as revenue
from dfs.tpch.lineorder_part l,
dfs.tpch.dates d,
dfs.tpch.custom
Hello Dmitry,
Welcome to Drill's community :)
What version of Drill are you using ?
Also, can you share the query profile of your query, it helps to show what
taking most of the time.
Thanks

One quick note here, I don't think partitioning LINEORDER table on
LO_ORDERDATE would help this query. If you look at the query profile you
will see that Drill is reading everything from LINEORDER.
