Action Concepts

A table stream has a set of StreamRecord-item-actionsAction. These specify an single operation that can happen to a stream-item (record) in the tablestream. RecordStream-item-actions can create, read, update or delete a record, so are called CRUD actions.

You can configure an Action to perform several operations on the data in different tablesstreams. This is because the action contains a list of recordstream-item-actions that can come from different tablesstreams.

The action can potentially run any of the recordstream-item-actions in its list. To decide which recordstream-item-action to run, the action has a rule associated with each recordstream-item-action. When a Stream Item Record-Action Rule evaluates to true, the action runs the action and therefore makes , making a change to the data in the tablestream.
