What is incremental aggregation and how it is done?

Answer Posted / ankit kansal

Incremental Aggregation ->

Incremental Aggregation is a technique to populate data on your aggregated tables or materialized view incrementally.

It takes new incoming data only based upon last updated column value or created_date time stamp column and thus uses its own cache created/updated earlier and updated the table as required.
