Designing the data handler

Before you begin to write a custom data handler, it is recommended that you clearly understand:

Creating a metadata-driven data handler

For your custom data handler to be metadata-driven, it must dynamically specify information that identifies the data handler to use. For more information on metadata-driven data handlers, see Metadata-driven data handler design.

Using data-handler meta-objects

One of the design decisions you need to make is whether you data handler will use meta-objects to initialize its configuration.

Note:
For more information about meta-objects, see Configuring data handlers.

Consider the following when deciding whether to use meta-objects:

If you design your custom data handler to use meta-objects, you need to create these meta-objects as part of your data-handler implementation. For more information, see Creating data-handler meta-objects.
