> Create module for Protobuf message-based client
> -----------------------------------------------
>
> Key: GEODE-4054
> URL: https://issues.apache.org/jira/browse/GEODE-4054
> Project: Geode
> Issue Type: Improvement
> Components: client/server
> Reporter: Michael Dodge
> Fix For: 1.4.0
>
>
> Create a module, geode-protobuf-client, that contains a simple Java client
> that exercises the Protobuf messages and the new protocol. This client should
> allow the interaction with a locator and cache server based on command-line
> arguments, a file of commands, or an interactive shell.
