We will show how we are building a clean and efficient incremental processing solution (IPS) by using Netflix Maestro and Apache Iceberg. This requires repopulating data for a historical time period which is before the scheduled processing. Users configure the workflow to read the data in a window (e.g. past 3 hours or 10 days).
