Chapter 17. Data Interoperability

Red Hat JBoss Data Grid offers multiple ways to interact with data, for example:

In previous versions of JBoss Data Grid, selecting one of these methods ensured that if one method was used to store data, the same method was required to retrieve it. For example, storing data in embedded mode required retrieval via embedded mode instead of a different method, for example using a REST endpoint.

JBoss Data Grid now offers a compatibility mode to allow users to access data with any interface regardless of the method used to store the data. In compatibility mode, the data format is automatically converted for each endpoint, which allows information to be stored and retrieved using different interfaces.

JBoss Data Grid's compatibility mode makes the following assumption about data: the most common use for compatibility mode is to store Java objects. As a result, when enabled, compatibility mode unmarshalls or deserializes data when storing it. This results in increased efficiency when using Java objects with an embedded cache.

Compatibility mode comes at a higher performance cost than non-compatibility mode. As a result, this feature is disabled by default in JBoss Data Grid.
