Hi,
I'm trying to run my query in parallel mode. I have setup my tables with " WITH(parallel_workers=2)" storage parameter and I've created indexes for needed attributes.
I have also set:
max_worker_processes = 100
max_parallel_workers_per_gather = 2
max_parallel_workers = 100
However, when I uses EXPLAIN to check the query plan, all of the nodes are set to "Parallel Aware"=false. Am I missing something?
Here is my tables and indexes:
CREATE TABLE t1(id int PRIMARY KEY, name varchar(200)) WITH(parallel_workers=2);
CREATE TABLE t2(id int PRIMARY KEY, fid int, value varchar(200)) WITH(parallel_workers=2);
CREATE INDEX ind_t1_id ON t1 USING HASH (id);
CREATE INDEX ind_t2_fid ON t2 USING HASH (fid);
Here's the query I tested with EXPLAIN:
SELECT * FROM t1 INNER JOIN t2 ON
t1.id = t2.fid WHERE
t1.id > 100;
