How Do Re-imported Tables Count towards MAR?

Question

How do re-imported tables count towards monthly active rows (MAR)?

Answer

Monthly active rows (MAR) are uniquely identified by a primary key. These keys are counted separately for each account, destination, connector, and table. Once a row is activated, it is only counted once per month - no matter how many updates are made that month.

When a table is re-imported on the first day of the month, the entire table counts towards your MAR (free and paid). For all subsequent days that month, only new records count towards your MAR.

Any re-imported table that is included in an initial sync counts towards free MAR on the day of the initial sync. Re-imported tables are counted as incremental rows on the day after the initial sync.

For example, see how re-imported tables are classified before a free trial, during a free trial, and on the first day of the month after a free trial:

Month 1, Day 1: An initial sync begins, and a re-imported table syncs 100 rows on this day. Moreover, the re-imported table will sync a new row each day. On this day, 100 rows are marked as counting towards free MAR.
Month 1, Day 2: The initial sync has not been completed, and the re-imported table synced one additional row. In total, 101 rows are marked as counting towards free MAR.
Month 1, Day 3: The initial sync has ended, and the free trial has started. On this day, 102 rows are re-classified as incremental.
Month 1, Day 16: The free trial ends today. We logged 102 rows as incremental on Day 3, and one additional row each day since then, for a total of 115 rows.
Month 1, Day 17: We update the incremental rows the day after the free trial ended, adding the 14 rows that the re-imported table synced every day since the free trial started. On this day, 116 rows are re-classified as incremental.
Month 1, Day 31: On this day, 116 rows are still classified as incremental, however the re-imported table synced an additional 14 rows since Day 17.
Month 2, Day 1: The re-imported table synced an additional 15 rows since Day 17. On this day, we mark 131 rows as counting towards MAR, leading to an increase in MAR.
