Delta Publishing of Data

The Delta Publish of catalog can also be referred to as incremental publish. When you have an environment with a considerable amount of table data, and if you make minor changes to the data, publishing all the data for a small increment takes a lot of time because the entire data set is published.

The Delta Publish feature addresses the issue by publishing only what has been changed. You can select the date and time and upon selection only those records are published which are created or modified after a selected date and time.

Delta Publish publishes records based on the last modified date of the record. The last modified date of the record is modified when the record attribute is modified.

• In case of PRODUCT table, if there are any changes to the offerID, the OfferIdMappings.xml file is also published.
• If you invoke Delta Publish for the first time on an environment, the entire data in the table is published.
