A simple and idiomatic Clojure facade around the Mesos JAVA API

Mesomatic provides facilities to interact with Apache Mesos from clojure. It provides a simple and idiomatic facade around the Mesos JAVA API and facilities to help when writing mesos frameworks.
Mesomatic versions match the API version they target, a trailing minor
indicates the patch release number, for instance version
Add this to your leiningen profile:
:dependencies [[clojusc/mesomatic "1.0.1-r1"]]
If you want to use the core.async facade, you will need to pull it in as well:
:dependencies [[clojusc/mesomatic "1.0.1-r1"] [clojusc/mesomatic-async "1.0.1-r1"]]
Be sure to examine the example frameworks built with mesomatic.
mesomatic.types: contains a facade to and from all protobuf types.
mesomatic.scheduler: facades for schedulers and scheduler-drivers
mesomatic.executor: facades for executors and executor-drivers
mesomatic.async.executor: produce executor callbacks on a channel
mesomatic.async.scheduler: produce scheduler callbacks on a channel
mesomatic.helpers: utility helpers for cluster decisions
To go to and from protobuf types, mesomatic uses two simple functions:
pb->data: yields a data structure from a mesos type, usually in the form of a record.
data->pb: converts a data structure to a mesos type.
->pb: convert a plain map to a mesos type hinted at by a keyword
By yielding records, mesomatic provides elements which are homomorphic to maps and can easily be converted back to protobuf.
A few cases do not yield records:
- Scalar values (
Protos.Value.Scalar) yield doubles.
- All enums yield keywords.
- Set values (
Protos.Value.Set) yield sets.
- Some types containing a single repeated field are unrolled
as a seq of their content, such as
- Target mesos 1.0.1
- Support for GPU resources
- Updates for API changes in Java bindings
