Questions tagged [change-data-capture]

Change data capture (CDC) encompasses database design patterns to keep track of changed data and perform actions with it.

In databases, change data capture (CDC) is a set of software design patterns used to determine (and track) the data that has changed so that action can be taken using the changed data. Also, Change data capture (CDC) is an approach to data integration that is based on the identification, capture and delivery of the changes made to enterprise data sources.

CDC solutions occur most often in data-warehouse environments since capturing and preserving the state of data across time is one of the core functions of a data warehouse, but CDC can be utilized in any database or data repository system.

what happens to a change-data-capture instance when the underlying table is altered?

If I enable change-data-capture for a table, and then somebody else adds a column to the table, will my capture be affected? Will I still get updates for the original columns? For the new column? What if a column is deleted?
