siddharthteotia commented on issue #1034: [CALCITE-2819] Add version of LoptOptimizeJoinRule that uses the first ordering it finds URL: https://github.com/apache/calcite/pull/1034#issuecomment-468449888 @vlsi ... we use this initially only to get some random ordering (not possibly the best ordering) to convert multi-join to join nodes.. There is probably no other way in Calcite to do that so added this unoptimized instance where we just return after getting the first ordering. So the test case also aims to verify if the result is the ordering by considering first join factor as the first factor.
