Re: Extremely irregular query performance

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Can I actully know whether a given plan is excuted with GEQO on ?
In other words, if I launch 'explain <query>', I'll get a given plan, but if I re-launch
the <query> (withtout the 'explain' keyword), could I get a different
plan given that GEQO induces some randomness ?

>Is it the plan that is different in the fastest case with GEQO or is it
>the time needed to plan that is causing the GEQO to beat the exhaustive
>search?
