Chapter 15. The REST Interface
15.1. The REST Interface
Red Hat JBoss Data Grid provides a REST interface, allowing for loose coupling between the client and server. Its primary benefit is interoperability with existing HTTP clients, along with providing a connection for php clients. In addition, the need for specific versions of client libraries and bindings is eliminated.
The REST API introduces an overhead, and requires a REST client or custom code to understand and create REST calls. It is recommended to use the Hot Rod client where performance is a concern.
To interact with Red Hat JBoss Data Grid’s REST API only a HTTP client library is required. For Java, this may be the Apache HTTP Commons Client, or the java.net API.
The following examples assume that REST security is disabled on the REST connector. To disable REST security remove the authentication and encryption elements from the connector.
15.2. The REST Interface Connector
15.2.1. The REST Interface Connector
The REST connector differs from the Hot Rod and Memcached connectors because it requires a web subsystem. Therefore configurations such as socket-binding, worker threads, timeouts, etc, must be performed on the web subsystem.
Once the REST interface has been enabled on the server it may be used normally for adding, removing, and retrieving data. For information on these processes refer to the JBoss Data Grid Developer Guide .
15.2.2. Configure REST Connectors
Use the following procedure to configure the rest-connector element in Red Hat JBoss Data Grid’s Remote Client-Server mode.
Configuring REST Connectors for Remote Client-Server Mode
<subsystem xmlns="urn:infinispan:server:endpoint:8.1">
<rest-connector cache-container="local"
context-path="${CONTEXT_PATH}"/>
</subsystem>
<subsystem xmlns="urn:infinispan:server:endpoint:8.1">
<rest-connector cache-container="local"
context-path="${CONTEXT_PATH}"/>
</subsystem>
The rest-connector element specifies the configuration information for the REST connector.
-
The
cache-containerparameter names the cache container used by the REST connector. This is a mandatory parameter. -
The
context-pathparameter specifies the context path for the REST connector. The default value for this parameter is an empty string (""). This is an optional parameter.
