Hello, CREATE INDEX i_n_regionkey ON nation (n_regionkey); CREATE INDEX i_s_nationkey ON supplier (s_nationkey); CREATE INDEX i_c_nationkey ON customer (c_nationkey); CREATE INDEX i_ps_suppkey ON partsupp (ps_suppkey); CREATE INDEX i_ps_partkey ON partsupp (ps_partkey); CREATE INDEX i_o_custkey ON orders (o_custkey); CREATE INDEX i_l_orderkey ON lineitem (l_orderkey); CREATE INDEX i_l_suppkey_partkey ON lineitem (l_partkey, l_suppkey); Even when I changed the query thread pool size I was unable to use more than one thread for a single query. I'm attaching you the file with which I created the tables. Thanks Best, Alessandro |
