Not yet. I would first like to know what is the time consuming part and what is a work around. If you are sure individual columns for every entry of the array solve the issue I will joyfully implement it. The downsize of this approch is that the array dimensions are not always the same in my scenario. But I have a workaround in mind for this issue.
The first thing I would try would be to completely normalize te file, aka create table data as ( id int, t timestamp, map_x int, map_y int, value float ); and go with denormalized approach only when this doesn't work for some reason. merlin
