>             Project: Mesos

> 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.
