About this task
Enable eXtreme Data Format (XDF) to store serialized objects
in a language independent manner. XDF is now the default serialization
technology that is used when you are running XIO and have a map copy
mode that is set to
COPY_TO_BYTES. When you
enable this feature, Java and
C# objects can share data in the same data grid. You can set XDF mode
for installations of
WebSphere® eXtreme Scale in
a stand-alone environment and for installations of
WebSphere eXtreme Scale within a
WebSphere Application Server environment.
When you
use XDF, you get the following benefits:
- Serialization of the data for sharing between Java, and C#/.NET
applications.
- Indexing data on the server without requiring the user classes
to be present, if field access is used.
- Automatic versioning of your classes so you can augment the class
definitions when you add applications that require newer versions
of the files. Older versions of the data can be used by taking advantage
of the Mergable interface.
- Partitioning of the data with annotations in Java and C# to consistently
partition from the application.
Restriction: You cannot use XDF if your data
grids have EntityMetadata defined.
What to do next
Develop applications that can share data. For more information,
