Pluton is a simple framework which makes network applications lighter-weight, easier to debug, lower latency and potentially less resource intensive. The core features of the framework include:

• an interface which encourages and simplifies parallel requests to reduce latency (without the complexity of threads!)

• a convenient, fast and simple API available in C, C++, php, perl and Java on FreeBSD and RHEL.

• encapsulation of services into self-contained, independent executables

• a serialization-agnostic interface between clients and services - you get to choose fast or pretty

Pluton was designed and developed by Mark Delany at Yahoo! and is used across many parts of the Yahoo network to substantially reduce web-serving latency and increase resiliency.

Except as specifically stated below, the 3rd party software packages are not distributed as part of this project, but instead are separately downloaded from the respective provider and built on the developer's machine as a pre-build step.
