Add LoadBalancingPolicy field to RevisionSpec in v1 API - Support policies: random-choice-2, round-robin, least-connections, first-available - Add validation for LoadBalancingPolicy in revision validation - Update CRD definitions for Configuration, Revision, and Service resources - Add validateLoadBalancingPolicy() to validate policy strings - Add pickLBPolicy() to select appropriate LB policy based on configuration - Convert lbPolicy and containerConcurrency to atomic types for thread-safe updates - Implement dynamic policy updates via revisionUpdated() method - Default policy selection based on container concurrency: - CC=0: random-choice-2 - CC=1-3: first-available - CC>3: round-robin - Fix leastConnectionsPolicy to use weight field instead of removed InFlight() - Add nil-safety checks to randomLBPolicy - Maintain existing policy implementations with minor safety improvements - Add LoadBalancingPolicy to defaults configuration - Update generated deepcopy methods for new field - Add TestLoadBalancingPolicySelection for policy selection logic - Add TestThrottlerUsesRevisionLoadBalancingPolicy for revision-level policies - Add TestDynamicLoadBalancingPolicyUpdate for runtime policy changes - Fix type mismatches (int32 vs uint32) in weight comparisons - Remove unused imports and variables - Maintain backward compatibility with existing pod tracking tests - Update serving-api.md with LoadBalancingPolicy field documentation This change enables users to configure load balancing behavior per revision. --- config/core/300-resources/configuration.yaml | 20 +- config/core/300-resources/revision.yaml | 20 +- config/core/300-resources/service.yaml | 20 +- docs/serving-api.md | 42 ++ pkg/activator/net/lb_policy.go | 104 +++- pkg/activator/net/throttler.go | 123 +++-- pkg/activator/net/throttler_test.go | 446 ++++++++++++------ pkg/apis/config/defaults.go | 2 + pkg/apis/config/zz_generated.deepcopy.go | 5 + pkg/apis/serving/metadata_validation.go | 11 + pkg/apis/serving/v1/revision_helpers_test.go | 2 +- pkg/apis/serving/v1/revision_types.go | 6 + pkg/apis/serving/v1/revision_validation.go | 4 + .../serving/v1/revision_validation_test.go | 98 ++++ pkg/apis/serving/v1/zz_generated.deepcopy.go | 5 + pkg/autoscaler/metrics/stat.pb.go | 3 +- test/test_images/grpc-ping/proto/ping.pb.go | 7 +- 17 files changed, 700 insertions(+), 218 deletions(-) diff --git a/config/core/300-resources/configuration.yaml b/config/core/300-resources/configuration.yaml index 4f82814a39b8..50afa60e8389 100644 --- a/config/core/300-resources/configuration.yaml +++ b/config/core/300-resources/configuration.yaml @@ -438,7 +438,7 @@ spec: type: object properties: host: -
