  1. Acquire Protobuf libraries for the target language of choice.

  2. Download the latest release of Geode and start a Geode server with the following gfsh commands:

    Start Server
    gfsh>start locator --name=locator --bind-address=localhost --port=10334
...
gfsh>start server --name=server --server-port=40404 --bind-address=localhost
...
gfsh>create region --name=SampleData --type=REPLICATE
Member | Status
------ | ----------------------------------------
server | Region "/SampleData" created on "server"
  3. Locate Protobuf message definition artifact from the downloaded Geode release. Directory $GEODE_HOME/tools/ClientProtocol/geode-protobuf-definitions-{versionNumber}.zip

  4. Unzip protobuf protocol message definitions. Using the relevant target language Protobuf library, generate the language bindings from the message definitions.

  5. Create your application that connects a TCP socket to the server running on the localhost, on port 40404.
  6. Write byte 110 to the socket.

  7. Build a handshake request message and write it in a delimited fashion to the socket.

    handshakeRequest
    handshakeRequest {
  version {
    major: 1
    minor: 0
  }
  authenticationMode: NONE
}
    handshakeResponse
    handshakeResponse {
  ok: 1
}
  8. Read the handshake response message in a delimited fashion from the socket and check the response for success.

  9. Build a put request message to put the value bar for the key foo and write it in a delimited fashion to the socket and read the put response message in a delimited fashion from it.

    putRequest
    message{ 
  putRequest {
    regionName: "testRegion"
      entry {
        key {
          stringResult: "foo"
        }
        value {
          stringResult: "bar"
        }
     }
  }
}
    putResponse
    message{ 
  putResponse {

}

  10. Verify the put with the following gfsh command:

    Verify Put
    gfsh>get --region=SampleData --key=foo
Result      : true
Key Class   : java.lang.String
Key         : foo
Value Class : java.lang.String
Value       : bar
