Línea de trabajo

Start in GrpcStorageOptions.Builder and follow resolveSettingsAndOpts() to see how InstantiatingGrpcChannelProvider is configured. Add the ChannelPoolSettings builder option, wire it through while preserving the unset default, and verify that the high-level Storage API exposes the configured pool settings.

api: storage

Is your feature request related to a problem? Please describe.

We use StorageOptions.grpc() with Direct Path on GKE for high-throughput writes (WriteChannel, resumable uploads). A single commit can trigger hundreds of concurrent uploads per pod.

GrpcStorageOptions builds InstantiatingGrpcChannelProvider without setChannelPoolSettings(), so the default is effectively one gRPC channel. With ~100+ concurrent RPCs, calls queue on that channel and we see high tail latency and underused bandwidth.

ChannelPoolSettings can be set on StorageSettings + StorageClient, but the high-level Storage API from StorageOptions.grpc().build().getService() offers no way to pass those settings.

(google-cloud-storage 2.34.0+, resolves to 2.55.x in our build.)

Describe the solution you'd like

Add setChannelPoolSettings(ChannelPoolSettings) to GrpcStorageOptions.Builder, wired through to InstantiatingGrpcChannelProvider in resolveSettingsAndOpts(). Default unchanged when unset.

Storage storage = StorageOptions.grpc()
    .setProjectId(projectId)
    .setChannelPoolSettings(ChannelPoolSettings.builder()
        .setInitialChannelCount(8)
        .setMaxChannelCount(16)
        .setMaxRpcsPerChannel(50)
        .build())
    .build()
    .getService();

Describe alternatives you've considered

  • StorageClient + custom StorageSettings — channel pool works, but not compatible with high-level Storage / WriteChannel.
  • Copy resolveSettingsAndOpts() in app code — fragile.
  • Upload concurrency limit in app — does not fix single-channel RPC queuing.
