I am currently working at a company where we're in the phase of choosing our new analytics tool. In this process we're (obviously) also comparing tools with each other and we're currently looking into "out-of-the-box" data availability.
This means that we're looking at how many rows are directly (not through an API) available in:
a normal report (as far as I know this is 50k, but I would like to know whether this is the right amount).
a data export/extract (scheduled or directly requested) (afaik: 50k)
a data warehouse export (The adobe help pages state this is unlimited and as I can recall this is correct but I would really like to know how many rows DWH can export from the interface).
a workspace report (afaik: 200 rows per breakdown).
Unique values (cardinality) (afaik: 500k, but could this be extended?)
