WL#1657: Better Dynamic Record Format with MyISAM
Affects: Server-7.1 — Status: Assigned — Priority: Medium
Re-design the layout of dynamic records in MyISAM so that we have less fragmentationin the data file and can do minor in-place record extension without record moving. This could perhaps be accomplished by a grid of N bytes on the file, so that every record segment occupies a multiple of this size and in the average has half of the grid room for in-place extension. Monty's suggestion, added by Trudy Pelzer 2005-10-03 Store fixed-size data in each row before dynamic-size data. (Note that this is common with other DBMSs.)
