I'm wondering how well MySQL compress data. I'm about to design a
database which will hold mainly _a lot_ of FLOAT-values, and since I do
not really know how well MySQL compress data or how I could calculate
this I'd really appriciate a little guidance.
Here's an example of how much data could be stored in a year:
1 value/minute are stored = 1440 values/day.
365 days / year.
We have 100 different tables with 25 columns each.
This makes 100*25*365*1440 = 1 314 000 000 values per year.
A typical value could be 25,5624.
How much space (in Mb) could this take up after a year do you think?
