23.2. Support for Non-Serializable Objects

A common user concern is whether Red Hat JBoss Data Grid supports the storage of non-serializable objects. In JBoss Data Grid, marshalling is supported for non-serializable key-value objects; users can provide externalizer implementations for non-serializable objects.
If you are unable to retrofit Serializable or Externalizable support into your classes, you could (as an example) use XStream to convert the non-serializable objects into a String that can be stored in JBoss Data Grid.

Note

XStream slows down the process of storing key-value objects due to the required XML transformations.
