Are the various facebook feeds incremental, or would they overwrite existing data with the last 180 days’ worth?
All of our data sources work in an upsert opreration - First update existing data and then insert new data. They determine if the data is old or new based on the primary key they have (APIs have default primary key so you don’t need to change that).
They will not delete any other existing data in the tables unless you mark the
truncate option under the data source’s advanced options.
