I managed to make the module into sufficiently good shape to at least not error out on Andres' example query. I tried it with SAIO, GEQO and the standard planner. from_collapse_limit and join_collapse_limit were set to 14. This was on a --enable-debug --disable-cassert -O2 build. Here are the results: SAIO, standard values saio_equilibrium_factor = 16 saio_temperature_reduction_factor = 0.95 time = too big SAIO, tweaked saio_equilibrium_factor = 12 saio_temperature_reduction_factor = 0.3 cost = 13376.10..19692.53 time = 86866.276 ms GEQO cost = 13936.53..19479.38 time = 182000.097 ms STANDARD cost = 17807.57..19339.64 time = 39361.248 ms A couple of remarks. The standard planner found a decent plan and only ate around 550 MB of memory while doing so. Reading this mail http://archives.postgresql.org/pgsql-hackers/2009-07/msg01219.php I was expecting it to start swapping, but for some reason it didn't. GEQO produced a comparable (even if a bit better) plan to SAIO and took quite some more time. OTOH, with the default parameters, SAIO takes crazy amounts of time and I never had the patience to even wait until it finishes. Memory usage stayed low in both, because both of them do calculations in a separate memory context that gets periodically reset. A short explanation on the saio_* parameter values. and the algorithm itself. The SAIO algorithm is composed of two loops: do { do { random_move() } while (!equilibrium()) reduce_temperature() } while (!frozen()) The inner loop does random moves until it reaches "equilibrium". Moves that improve the plan are always accepted, uphill moves are accepted with the probability that's proportional to how much worse the new plan is and how high the current temperature is. The paper I quoted earlier that equilibrium is reached after iterating the inner loop 16 * number_of_joins times. The "16" parameter is what I called saio_equilibrium_factor. In each outer loop iteration the temperature of the system is reduced by a factor of saio_temperature_reduction_factor, which is 0.9 in the paper. The catch is that because of join order constraints, lots of random moves are resulting simply invalid and are rejected, even if they still are counted as a full iteration of the inner loop. ISTM that it doesn't skew the results too much, though. I followed Tom's advice to mimick GEQO's way of choosing joins with join clauses first, but that only is done when building the starting tree. After that the moves are random. A related question: why does GEQO try to put the largest "clumps" at the beginning of the list? Is it to achieve maximum left-deepness? I didn't copy that in SAIO, I'm just adding the new clump at the beginning of the list. The big question for me now is what are the reasonable values of those two GUCs? I think that because of the amount of work make_join_rel does (handle symmetric case, consider all access paths) they can be made stricter that in the paper, so 16/0.9 seems wrong. OTOH, I have no idea why it takes so long with those parameters cranked up, I would think they influence the running time linearly, but maybe I'm just way off base. For the record, I'm attaching oprofile results for the standard planner, GEQO and SAIO (standard and tweaked, I ctrl+c'd the standard run). I was profiling the whole system, but what I'm attaching is the grepped out "postgres" part. What I don't get is why cranking up the GUCs results in generate_join_implied_equalities moving to the top of the list. I've spent countless hours trying to understand why that happens and am currently at a loss. > Robert had another example in > 603c8f070911271205r4d4534edt1cebcb76ff5066a5@mail.gmail.com that might be > interesting. I'll give it a shot soon, and then hopefully will do some plan quality comparision on less pathological queries.
