Re: how to calculate the size of the database with the ndb_size.pl script

[Stewart Smith]

You need to do some calculations yourself too :)

I haven't incorporated a patch for a "total database size" summary at the end yet (it's on that list of things to do - along with some of the MaxOf parameters).

As for how much RAM is needed - sum up total DataMemory and total IndexMemory and that should be enough to hold your current database.

Working out how much extra space you need for the future is an exercise for the reader :)

That's why i give you the "rows per page" value - so you can get pretty good estimates for doing your calculations.
