Proxy Store

The proxy store is simply a Gaffer store implementation which delegates all operations to a Gaffer REST API. See Javadoc.

Using a proxy store with Gaffer REST

These are the full set of configurable properties which can be used in .properties config file with Gaffer REST:

  • gaffer.host: Hostname or IP Address of the Gaffer REST API
  • gaffer.port: Port for the Gaffer REST API
  • gaffer.context-root: The path to use as the context root
  • gaffer.connect-timeout: Connect timeout in milliseconds
  • gaffer.read-timeout: Read timeout in milliseconds

For more information on the timeouts, see the docs for the Jersey client which is used internally.

Example store.properties config file 
gaffer.store.class=uk.gov.gchq.gaffer.proxystore.ProxyStore
gaffer.host=example.hostname
gaffer.port=8080
gaffer.context-root=/rest/v2

Using a ProxyStore from Java

To create a ProxyStore you just need to provide a host, port and context root. This can be done via the ProxyStore.Builder: 

Graph graph = new Graph.Builder()
    .store(new ProxyStore.Builder()
            .graphId(uniqueNameOfYourGraph)
            .host("localhost")
            .port(8080)
            .contextRoot("rest/v1")
            .build())
    .build();

You can then write your queries in Java and the ProxyStore will convert them into JSON and execute them over the REST API.
