A stream object records/captures data manipulation language (DML) changes made to a table, including inserts, updates, and deletes, as well as metadata about each change, so that actions can be taken using the changed data (rows & fields). This process is referred to as change data capture (CDC). An individual table stream tracks the changes made to rows in a source table. A table stream (also referred to as simply a "stream") makes a "change table" available of what changed, at the row level, between two transactional points of time in a table. Stream also allows querying and consuming a sequence of change records in a transactional fashion.
