Change subject: Commit for onetoone join
......................................................................
Patch Set 2:
Oh. Actually, the original issue78 gives a situation where asterixdb will
enforce hash partition for both LineItem and PS due to the containment
verification from join requirement (top-down) to the delivery (bottomup). i.e.
Requirement (ps_partkey, ps_suppkey, ps_supplycost) dependents on
pk(ps_partkey, ps_suppkey), so the hash_partition is NOT necessary.
for $li in dataset('LineItems')
for $ps in dataset('PartSupp')
where $li.l_partkey = $ps.ps_partkey and $li.l_suppkey = $ps.ps_suppkey and
$li.l_extendedprice = $ps.ps_supplycost
return {
"l_partkey": $li.l_partkey
}
