Chapter 44. Endpoint Interoperability

You can configure key and values with a text-based storage format.

For example, specify text/plain; charset=UTF-8, or any other character set, to set plain text as the media type. You can also specify a media type for other text-based formats such as JSON (application/json) or XML (application/xml) with an optional character set.

The following example configures the cache to store entries with the text/plain; charset=UTF-8 media type:

<cache>
   <encoding>
      <key media-type="text/plain; charset=UTF-8"/>
      <value media-type="text/plain; charset=UTF-8"/>
   </encoding>
</cache>

To handle the exchange of data in a text-based format, you must configure Hot Rod clients with the org.infinispan.commons.marshall.StringMarshaller marshaller.

REST clients must also send the correct headers when writing and reading from the cache, as follows:

Storing data in the cache as Protobuf encoded entries provides a platform independent configuration that enables Java and Non-Java clients to access and query the cache from any endpoint.

If indexing is configured for the cache, JBoss Data Grid automatically stores keys and values with the application/x-protostream media type.

If indexing is not configured for the cache, you can configure it to store entries with the application/x-protostream media type as follows:

<distributed-cache name="my-cache">
   <encoding>
      <key media-type="application/x-protostream"/>
      <value media-type="application/x-protostream"/>
   </encoding>
</distributed-cache>

JBoss Data Grid converts between application/x-protostream and application/json, which allows REST clients to read and write JSON formatted data. However REST clients must send the correct headers, as follows:

Read: Accept: application/json

Write: Content-Type: application/json
