---------------------------------------
Summary: Expose lower-level scheduler/executor API
Key: MESOS-1127
URL: https://issues.apache.org/jira/browse/MESOS-1127
Project: Mesos
Issue Type: Improvement
Components: framework
Reporter: Benjamin Hindman
Assignee: Benjamin Hindman
The default scheduler/executor interface and implementation in Mesos have a few
drawbacks:
(1) The interface is fairly high-level which makes it hard to do certain
things, for example, handle events (callbacks) in batch. This can have a big
impact on the performance of schedulers (for example, writing task updates that
need to be persisted).
(2) The implementation requires writing a lot of boilerplate JNI and native
Python wrappers when adding additional API components.
The plan is to provide a lower-level API that can easily be used to implement
the higher-level API that is currently provided. This will also open the door
to more easily building native-language Mesos libraries (i.e., not needing the
C++ shim layer) and building new higher-level abstractions on top of the
lower-level API.
