// Package allocator aims to manage allocation of different
|
|
// cluster-wide resources on behalf of the manager. In particular, it
|
|
// manages a set of independent allocator processes which can mostly
|
|
// execute concurrently with only a minimal need for coordination.
|
|
//
|
|
// One of the instances where it needs coordination is when to move a
|
|
// task to ALLOCATED state. Since a task can move to ALLOCATED state
|
|
// only when all task allocators have completed their service of
|
|
// allocation, they all have to agree on that. The way this achieved
|
|
// in `allocator` is by creating a `taskBallot` to which all task
|
|
// allocators register themselves as mandatory voters. For each task
|
|
// that needs allocation, each allocator independently votes to indicate
|
|
// the completion of their allocation. Once all registered voters have
|
|
// voted then the task is moved to ALLOCATED state.
|
|
//
|
|
// Other than the coordination needed for task ALLOCATED state, all
|
|
// the allocators function fairly independently.
