This introduces the key components of partitioned execution.
- `sparrow-scheduler` provides functionality for managing the separate
pipelines within the query plan and morsel-driven parallelism. It
managing a thread-pool of workers pinned to specific CPUs pulling
tasks from local queues.
- `sparrow-transforms` will provide implementations of the "transforms"
(project, select, etc.) and a pipeline for executing the transforms.
- `sparrow-execution` will pull everything together to provide
partitioned execution.
TODO (before merge or move to ticket):
- [ ] Cleanup implementation / review naming
- [ ] Reduce the number of top-level fields in PipelineTransform, if
possible.
- [ ] Implement at least one `Sink` and `Source`
- [ ] Update sparrow execution to actually tie things together.
- [ ] Add unit tests for sparrow execution demonstrating everything
working together.
- [ ] Add loom tests for the `TransformPipeline`
- [ ] Add loom tests to CI
