This PR enables stage fusion for dataset pipelines. This also requires:
1. Removing the num_cpus=0.5 default for the read stage, to enable fusion of the read stage.
2. Removing spread_resource_prefix (not supported for now).
- Separate spread scheduling and default hydra scheduling (i.e. SpreadScheduling != HybridScheduling(threshold=0)): they are already separated in the API layer and they have the different end goals so it makes sense to separate their implementations and evolve them independently.
- Simple round robin for spread scheduling: this is just a starting implementation, can be optimized later.
- Prefer not to spill back tasks that are waiting for args since the pull is already in progress.
It seems like the S3 read sometimes fails; #22214. I found out the file actually does exist in S3, so it is highly likely a transient error. This PR adds a retry mechanism to avoid the issue.
Fix dash on ray large scale test on K8s. Basically, chmod requires a root access, which we don't have it by default in the k8s cluster. We don't need chmod I think (I verified the test passes without it).
The first migration of test into k8s. We are adopting a conservative approach (migrate slowly while we keep existing test suites). Once things are confirmed to be stable, we will migrate with more speed.
This fixes the previous problems from team column revert.
This has 2 additional changes;
alert handler receives the team argument, which was the root cause of breakage; https://github.com/ray-project/ray/pull/21289
Previously, tests without a team column were raising an exception, but I made the condition weaker (warning logs). I will eventually change it to raise an exception, but for smoother transition, we will log warning instead for a short time
RAY_GCS_ACTOR_SCHEDULING_ENABLED is wrong should be RAY_gcs_actor_scheduling_enabled. Since gcs based actor scheduling is not enabled yet so I just removed this flag.
Expands the `to_torch` method for Datasets with:
* An ability to choose to output a list/dict of feature tensors instead of just one (through setting `feature_columns` to be a list of lists or a dict of lists)
* An ability to choose whether the label should be unsqueezed or not
* An ability to pass `None` as the label (for prediction).
Furthermore, this changes how the `feature_column_dtypes` argument works. Previously, it took a list of dtypes for each feature. However, as the tensor was concatenated in the end, only one dtype mattered (the biggest one). Now, this argument expects a single dtype which will be applied to the features tensor (or a list/dict if `feature_columns` is a list of list/dict of lists).
Unit tests for all cases are included.

Please review **e2e.py and test_suite belonging to your team**!
This is the first part of https://docs.google.com/document/d/16IrwerYi2oJugnRf5hvzukgpJ6FAVEpB6stH_CiNMjY/edit#
This PR adds a team name to each test suite.
If the name is not specified, it will be reported as unspecified.
If you are running a local test, and if the new test suite doesn't have a team name specified, it will raise an exception (in this way, we can avoid missing team names in the future).
Note that we will aggregate all of test config into a single file, nightly_test.yaml.
This adds memory monitoring to scalability envelope tests so that we can compare the peak memory usage for both nonHA & HA.
NOTE: the current way of adding memory monitor is not great, and we should implement fixture to support this better, but that's not in progress yet.
we fixed groupby issue in cuj2; sync the change into nightly test. this test doesn't need to use gpu at all. it returns soon after data ingestion finishes.
This PR does two things:
merge latest groupby based filtering to CUJ2
add a debug mode so we only run dummy trainer for measure data processing performance.
This PR is mostly for implementing "fixture" for nightly test. Note that the current fixture implementation is not that great, and we can probably improve this in the future after refactoring e2e.py.
