------------------------------------
Summary: Consider supporting multiple tasks per executor
Key: AURORA-154
URL: https://issues.apache.org/jira/browse/AURORA-154
Project: Aurora
Issue Type: Epic
Components: Executor
Reporter: brian wickman
Priority: Minor
Support multiple tasks per executor; decouple lifecycle of task from lifecycle
of executor.
Thermos gives the ability to colocate multiple related processes together
within a single task, however you cannot update these processes independently
of the task.
If we could decouple the lifecycle of a task from the lifecycle of the executor
and/or support multiple tasks within a single executor (and hence its cgroup),
we could explore more interesting use-cases such as being able to update tasks
while keeping the sandbox intact. This would be useful for heavily stateful
services, especially if we can eventually provide stronger guarantees about the
lifecycle of the executor (e.g. if mesos ever supports executors that persist
across machine restarts / task loss.)
