Cohorts are useful to determine a grouping of data across a date dimension. For example, how many users remain active n months after initial signup, etc.
We currently support 2 types of input data.
select COHORT(<Date Column>, <Cohort Date Definition>, <Cohort Period Definition>), <Cohort Operation>
group by <Cohort Date>, <Cohort Period>
Note:
Input data needs to be sorted by Date ascending order.
Cohort Period returns a number (ie: the period) or a date. Example:
a. 1m: Cohort Period as number
b. (1m): Cohort Period as Date
