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 1.0.1-r0 will target mesos 1.0.1.
Add this to your leiningen profile.
:dependencies [[org.spootnik/mesomatic "1.0.1-r0"]]If you want to use the core.async facade, you will need to pull it in as well:
:dependencies [[org.spootnik/mesomatic "1.0.1-r0"]
[org.spootnik/mesomatic-async "1.0.1-r0"]]See example frameworks built with mesomatic at https://github.com/clojusc/mesomatic-examples
mesomatic.types: contains a facade to and from all protobuf types.mesomatic.scheduler: facades for schedulers and scheduler-driversmesomatic.executor: facades for executors and executor-driversmesomatic.async.executor: produce executor callbacks on a channelmesomatic.async.scheduler: produce scheduler callbacks on a channelmesomatic.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
Protos.Value.Ranges.
- Target mesos 1.0.1
- Support for GPU resources
