The text discusses the value of the memcached ecosystem, emphasizing the importance of well-defined client APIs and an over-the-network protocol, which is beneficial for a wide array of applications. It highlights the existence of numerous clients across various platforms and languages, noting the straightforwardness of implementing the protocol's basics, leading to many partial clients. The text also addresses the need for a tool to quickly assess protocol compliance in implementations, which was realized through the creation of "memcapable," a utility incorporated into libmemcached. This tool, developed through collaboration among developers, including the author, Brian Aker, and Trond, serves to help users determine the extent to which new implementations support the memcached protocol. The text concludes with an example of Patrick Galbraith using memcapable to evaluate Tokyo Tyrant, illustrating the tool's practical application.
