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:

   Code Block
   language bash theme Emacs title Start Server
   startgfsh>start locator --name=locator --bind-address=localhost --port=10334 ... gfsh>start server --name=server --server-port=40404 --bind-address=localhost ... creategfsh>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.
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.

10. Read the put response message in a delimited fashion from the socket

    .

    and verify the put with the following gfsh command:

    Code Block
    language bash theme Emacs title Verify Put

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