Fix the failure to unbreak nightly and unblock 1.13 release.
The root cause is the upgrade of GRPC to 1.45.2 made it slightly slow; this is an acceptable regression which is needed to make this upgrade.

To facilitate easy demo/documentation/testing with realistic, small-sized yet ML-familiar data. Have it as a source file with code will make it self-contained, i.e. after user "pip install" Ray, they are all set to run it.
IRIS is a great fit: super classic ML dataset, simple schema, only 150 rows.
This is a notebook showing how to tune an xgboost model and analyze the results.
Also adds a `get_dataframe()` method to `ResultsGrid` to fetch the trial results.
Depends on #24483 for toctree.
Aiming to:
1. addressing the bug about concurrency group, see #19593
2. improving the stability of the ray call latency perf in online applications.
we're proposing using async post instead of `PostBlocking` in threadpool.
Note that since we have already had back pressure in the caller side, I believe this change is safe to merge and it doesn't break any behavior.
This PR uses the job id and group name as the prefix for storing meta information, aiming to provide the isolate ability for different jobs and different groups.
Before this PR, we can't use 2 groups in 1 Ray cluster, and we can not rerun a collective job once the last one is failed at initializing.
Some tests relying on AutoScalingCluster are flaky because ray.init() after AutoscalingCluster.start() is not guaranteed to work. Sometimes, it cannot find any running ray instances.
This was a holdover from when local resources for URIs were deleted directly from the runtime env agent, and the URI name itself needed to store the information of which plugin it corresponded to so the appropriate plugin's `delete()` function could be called. After the URI reference refactor, I don't think this is needed anymore.
Adds `get_dataframe()` method to pass through experiment analysis to result grid. Also fixes config dictionary returns which previously did not flatten the dict (even though the docstring suggested it would)
This PR supports setting the jars for an actor in Ray API. The API looks like:
```java
class A {
public boolean findClass(String className) {
try {
Class.forName(className);
} catch (ClassNotFoundException e) {
return false;
}
return true;
}
}
RuntimeEnv runtimeEnv = new RuntimeEnv.Builder()
.addJars(ImmutableList.of("https://github.com/ray-project/test_packages/raw/main/raw_resources/java-1.0-SNAPSHOT.jar"))
.build();
ActorHandle<A> actor1 = Ray.actor(A::new).setRuntimeEnv(runtimeEnv).remote();
boolean ret = actor1.task(A::findClass, "io.testpackages.Foo").remote().get();
System.out.println(ret); // true
```
This PR support reconnection of the GCS client in gRPC channel layer. Previously this is implemented in the application layer:
- Health check is in the application layer by starting a new channel.
- Monitor the GCS address change and do resubscribe.
- Always retry the failed request and do reconnection in case of a failure.
However, there are several issues with this approach:
- We need service to discover for GCS address change.
- Monitor is too heavy since it always creates a channel.
- Reconnection is a blocking call that prevents the code from running.
This new approach moves the reconnection to gRPC layer directly to fix these issues.
- DNS name resolution is done by gRPC so we don't need to write this.
- Health check is done by checking the channel state.
- Queue the failed call and retry once GCS is up so that it's not a blocking call.
Under heap memory pressure, the raylet is often killed by the OS OOM killer. This is bad because it can cause whole system crashes and it is difficult to find the error afterwards. This PR adjusts the OOM score for any workers that the raylet spawns so that the OOM killer will hopefully prioritize killing those instead of the raylet.
This is a small update for the structure of the docs about building Ray from source.
My idea was to isolate steps that are shared and then steps required per platform/system. Also consolidating the instructions to clone with git, install, directory structure, etc.
I'm still figuring out the building steps (installing the dependencies for docs in an M1), but I wanted to start the draft right away.
Adds support for chunking large schedule calls. Needed to support ray.remote calls with more than 2GiB of arguments.
Deprecates the args and kwargs fields of ClientTask and replaces them with a data field that contains a tuple of the serialized args and kwargs fields, which can be chunked and reassembled more easily using the same logic as PutRequest's.
A simple way to redirect remote job output to a custom file is extremely useful.
Especially if it does not require any code changes for the user, and especially if it captures all output and not limited only to python logging.
When the PR will be merged, the user will be able to do the following (for example):
ray submit some_cluster_config.yaml example_runnable_script.py --screen --extra-screen-args "-Logfile /gpfs/usr/someone/ray/output_log.txt"
which will, in addition to creating the screen session, also output (continuously) to custom text file.
It allows additional flexibility, for example, the user will be able to choose custom screen session name etc.
Closes#24514 by filtering out pods with metadata.deletionTimestamp set in the KuberayNodeProvider.
Adds some e2e test logic to confirm reasonable behavior when Ray worker pod termination hangs.
Also, a bit of code cleanup -- defining constants, adding to doc strings, etc.
HEBOSearch algorithm currently fails if the config search space contains a categorical parameter where each category is an iterable.
For instance, choosing the hidden layers of a NN:
` hyperparam_search_space = {'hidden_sizes': tune.choice([[512, 256, 128], [1024, 512, 256]])}`
This is due to the creation of the Pandas DataFrame with HEBO suggested parameters, without explicitly telling Pandas that the hyper-parameter suggestion is a single row of data while the index is being defined as a single row. This results in an exception such as "ValueError: Length of values (3) does not match length of index (1)".
