Changes: - IThrottleTracker: Add ThrottledConnectionCount, ThrottledConnections, GetShortestExpiry() for routing decisions - ThrottleTracker: Implement new methods with CleanupExpired() helper - BulkOperationExecutor: - Add IThrottleTracker dependency - Add TryGetThrottleInfo() to detect service protection errors (error codes -2147015902, -2147015903, -2147015898) - Extract Retry-After from OrganizationServiceFault.ErrorDetails - Add ExecuteBatchWithThrottleHandlingAsync() wrapper for retry logic - Intelligent routing: try different connection first, wait only when all connections are throttled - Refactor all batch methods (Create, Update, Upsert, Delete) to use the throttle-aware wrapper Behavior: 1. On throttle, RecordThrottle() is called to mark the connection 2. If other connections available, retry immediately on different one 3. If all throttled, wait for shortest expiry + 1s buffer 4. Max 3 retries before throwing ServiceProtectionException This completes the throttle tracking infrastructure so that ThrottleAwareStrategy actually routes away from throttled connections. πŸ€– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- .../BulkOperations/BulkOperationExecutor.cs | 335 ++++++++++++++++-- .../Resilience/IThrottleTracker.cs | 17 + .../Resilience/ThrottleTracker.cs | 62 ++++ 3 files changed, 393 insertions(+), 21 deletions(-) diff --git a/src/PPDS.Dataverse/BulkOperations/BulkOperationExecutor.cs b/src/PPDS.Dataverse/BulkOperations/BulkOperationExecutor.cs index ac9362a95..94cd52ebf 100644 --- a/src/PPDS.Dataverse/BulkOperations/BulkOperationExecutor.cs +++ b/src/PPDS.Dataverse/BulkOperations/BulkOperationExecutor.cs @@ -3,6 +3,7 @@ using System.Collections.Generic; using System.Diagnostics; using System.Linq; +using System.ServiceModel; using System.Threading; using System.Threading.Tasks; using Microsoft.Extensions.Logging; @@ -13,6 +14,7 @@ using PPDS.Dataverse.DependencyInjection; using PPDS.Dataverse.Pooling; using PPDS.Dataverse.Progress; +using PPDS.Dataverse.Resilience; namespace PPDS.Dataverse.BulkOperations { @@ -27,7 +29,18 @@ public sealed class BulkOperationExecutor : IBulkOperationExecutor /// private const int MaxPoolExhaustionRetries = 3; + /// + /// Maximum number of retries when service protection limits are hit. + /// + private const int MaxThrottleRetries = 3; + + /// + /// Fallback Retry-After duration when not provided by the server. + /// + private static readonly TimeSpan FallbackRetryAfter = TimeSpan.FromSeconds(30); + private readonly IDataverseConnectionPool _connectionPool; + private readonly IThrottleTracker _throttleTracker; private readonly DataverseOptions _options; private readonly ILogger _logger; @@ -35,14 +48,17 @@ public sealed class BulkOperationExecutor : IBulkOperationExecutor /// Initializes a new instance of the class. /// /// The connection pool. + /// The throttle tracker for recording service protection events. /// Configuration options. /// Logger instance. public BulkOperationExecutor( IDataverseConnectionPool connectionPool, + IThrottleTracker throttleTracker, IOptions options, ILogger logger) { _connectionPool = connectionPool ?? throw new ArgumentNullException(nameof(connectionPool)); + _throttleTracker = throttleTracker ?? throw new ArgumentNullException(nameof(throttleTracker)); _options = options?.Value ?? throw new ArgumentNullException(nameof(options)); _logger = logger ?? throw new ArgumentNullException(nameof(logger)); } @@ -393,16 +409,225 @@ private async Task GetClientWithRetryAsync(CancellationToken canc throw new InvalidOperationException("Unexpected code path in connection pool retry logic"); } - private async Task ExecuteCreateMultipleBatchAsync( + /// + /// Checks if an exception is a service protection throttle error and extracts the Retry-After duration. + /// + /// The exception to check. + /// The Retry-After duration if this is a throttle error. + /// The service protection error code if this is a throttle error. + /// True if this is a service protection error. + private bool TryGetThrottleInfo(Exception exception, out TimeSpan retryAfter, out int errorCode) + { + retryAfter = TimeSpan.Zero; + errorCode = 0; + + // Check if this is a FaultException with OrganizationServiceFault + if (exception is not FaultException faultEx) + { + return false; + } + + var fault = faultEx.Detail; + errorCode = fault.ErrorCode; + + // Check if this is a service protection error + if (!ServiceProtectionException.IsServiceProtectionError(errorCode)) + { + return false; + } + + // Extract Retry-After from ErrorDetails + if (fault.ErrorDetails != null && + fault.ErrorDetails.TryGetValue("Retry-After", out var retryAfterObj)) + { + if (retryAfterObj is TimeSpan retryAfterSpan) + { + retryAfter = retryAfterSpan; + } + else if (retryAfterObj is int retryAfterSeconds) + { + retryAfter = TimeSpan.FromSeconds(retryAfterSeconds); + } + else if (retryAfterObj is double retryAfterDouble) + { + retryAfter = TimeSpan.FromSeconds(retryAfterDouble); + } + else + { + _logger.LogWarning( + "Unexpected Retry-After type: {Type}.
