## Configuring Before-images Streaming

Learn to configure streaming before-images using the Oracle NoSQL Database Streams API.

You can optionally configure the subscription to enable before-images in the streamed events using the `setIncludeBeforeImage()` method as follows:

    final NoSQLSubscriptionConfig subConfig =
        new NoSQLSubscriptionConfig.Builder("ChkptTable")
        .setSubscribedTables("UserTable")
        .setStreamMode(NoSQLStreamMode.FROM_NOW)
        .setIncludeBeforeImage(true)
        .build();

As a pre-requisite, you must have enabled before-images generation for the subscribed table. For details, see Enabling Before-images During Table Creation
