[dependabot]

Bumps ray from 2.46.0 to 2.49.2.

Release notes

Sourced from ray's releases.

Ray-2.49.2

There is no difference between 2.49.2 and 2.49.1, though we needed a patch version for other out of band reasons. To fill the awkward blankness, here is a haiku about Ray:

Summit drawing near Ray advances, step by step Scaling without end

Ray-2.49.1

• Ray Dashboard: Fix issue where GPU metrics are missing (#56006)
• Ray Data: Fixed regression in handling very large schemas (#56058)

Ray-2.49.0

Release Highlights

Ray Data:

• We’ve implemented a variety of performance enhancements, including improved actor/node autoscaling with budget-aware decisions; faster/more accurate shuffle accounting; reduced Parquet metadata footprint; and out-of-order execution for higher throughput.
• We’ve also implemented anti/semi joins, stratified train_test_split, and added Snowflake connectors.

Ray Core:

• Performance/robustness cleanups around GCS publish path and raylet internals; simpler OpenTelemetry flagging; new user-facing API to wait for GPU tensor free; plus assorted test/infra tidy-ups

Ray Train:

• We’ve introduced a new JaxTrainer with SPMD support for TPUs.

Ray Serve:

• Custom Autoscaling per Deployment Serve now supports user-defined autoscaling policies via AutoscalingContext and AutoscalingPolicy, enabling fine-grained scaling logic at the deployment level. This is part of a large effort where we are adding support for autoscaling based on custom metrics in Serve, see this RFC for more details.
• Async Inference (Initial Support): Ray Serve introduces asynchronous inference execution, laying the foundation for better throughput and latency in async workloads. Please see this RFC for more details.
• Major Performance Gains: This version of ray serve brings double digit % performance improvements both in throughput and latency. See release notes for more details.

Ray Serve/Data LLM:

• We’ve refactored Ray Serve LLM to be fully compatible with the default vllm serve and also now supports vLLM=0.10.
• We’ve added a prefix cache-aware router with PrefixCacheAffinityRouter for optimized cache utilization; dynamic cache management via reset prefix cache remote methods; enhanced LMCacheConnectorV1 with kv_transfer_config support.
