That’s right, store as much data (values/rows) as you need without increasing costs, as you are only charged by the number of columns (attributes and events) you have, not by the volume of data you insert on your columns. Amazing, right?
We believe you shouldn't be punished financially just because you collect and analyze lots of data.
Monthly price = number of Attribute Columns + Event Columns (by data retention time) + Query Load.
($ 15.50 = 2 attribute columns ($ 3.00) + 10 event columns (30 days data retention) ($ 2.50) + small load ($ 10.00))
