I have a large data set (15 mil rows) consisting of a datetime column and a char(255) column. I seem to recall seeing something about performance benefits for using static length rows with MyISAM tables, and I've heard some argument for using dynamic length rows (e.g., use varchar rather than char) in InnoDB tables. So for performance sake (assuming no index can be used), which is better for these table types?
I can imagine that using dynamic length would be better in the case of an IO bottleneck, but maybe there is an efficiency gain from knowing where the records start and stop ahead of time..?
