How do re-imported tables count towards Monthly Active Rows (MAR)?
For a table that re-imports (re-syncs) (e.g. once per day), the entire table is counted towards MAR on the first day of the month. Every subsequent day, only new records are counted as MAR.
A Monthly Active Record is uniquely identified by it's primary key. Every time we see a record with the primary key, we know it is the same record we already observed that month. It is not counted as additional MAR.
