Backfill
Retroactively processing historical data through a new automation after it is deployed. Example: after building an invoice automation, running it against 6 months of existing orders to populate historical records.
Expert insight
Backfilling historical data through a workflow built for real-time events risks re-triggering side effects meant to happen once, sending a "welcome" email to 10,000 existing contacts because a new automation was pointed at historical data instead of only new records going forward. Backfills need their own logic path that skips side effects like notifications.
How PURIST uses this
This concept is built into every automation we deploy.
When PURIST builds your automation, Backfill is not an optional consideration it is part of the production standard. Our workflows are tested against edge cases, monitored 24/7, and built to handle what happens when things don't go as expected.
Every client workflow we deploy in the Data category is designed with this principle in mind from day one not added as an afterthought.
Complexity level
Requires some familiarity with automation concepts.
