Description

See "src/state/state.hpp" and "src/java/src/org/apache/mesos/state/*.java" for what the "state abstraction" is.

With the new HTTP API (see MESOS-2288, MESOS-2289), there will be no need to link to libmesos to a framework for it to communicate with a Mesos master. However, if a framework uses the Mesos "state abstraction", either directly in C++ or through other language bindings (e.g., Java), it still needs to link with libmesos. So, in order to achieve libmesos-free frameworks that can leverage all APIs Mesos has to offer, we need a different way to access the "state abstraction".

—

One approach is to provide an HTTP API for state queries that get routed through the Mesos master, which relays them by making calls into libmesos. Details TBD, including how separate this will be from the general HTTP API.
