Proto.Actor implementation for ChangeTokenSignalPublisher (#5817) * Refactor ProtoActor modules and integrate new core module Removed obsolete proto actor-related files and introduced a new core module under `Elsa.ProtoActor.Core` to centralize ProtoActor functionalities. Updated services and extensions to align with the new core structure, focusing on efficient persistence and actor system configurations. * Add Proto.Actor-based distributed caching module Introduces a new module `Elsa.Caching.Distributed.ProtoActor` for Proto.Actor-based distributed caching, including configuration extensions, proto files, and required services. Refactors some existing Proto.Actor-related features and updates Dockerfile and example projects to use the new module. * Refactor ProtoActor cache handling and virtual actor setup. Reorganize the distributed caching by introducing LocalCacheVirtualActorProvider and StartLocalCacheActor. Update WorkflowInstanceVirtualActorProvider for better cluster kind handling. Adjust namespaces in Protobuf definitions for consistency. * Refactor LocalCacheImpl to use IChangeTokenSignalInvoker Replace IChangeTokenSignaler with IChangeTokenSignalInvoker to align with updated dependency contract. Adjust method call to use InvokeAsync for triggering token signals with cancellation support. * Refactor ConfigureClusterConfig and config mutation Change ConfigureClusterConfig from Action to Func for better flexibility. Update clusterConfig and remoteConfig to support reassignment from configuration methods. * Add ProtoActor support for distributed caching Introduced ProtoActor as a new distributed caching transport option. Updated the configuration and workflow runtime settings to utilize ProtoActor. Added necessary project reference for Elsa.Caching.Distributed.ProtoActor in the .csproj file. * Add LocalNodeStrategy and integrate it in actor provider Introduced `LocalNodeStrategy` to handle member placement on the current node. Integrated the new strategy in `LocalCacheVirtualActorProvider`, ensuring it uses `LocalNodeStrategy` for member management. * Prevent duplicate member additions based on ID. Updated the member checking logic to include member IDs. In addition, this change improves the robustness of the member management in `LocalNodeStrategy.cs`. * Refactor virtual actor configuration into a separate method Moved virtual actor setup logic from `ProtoActorFeature` to a new `AddVirtualActors` method to improve code readability and reusability. Updated related files to maintain consistency and enhance documentation clarity. * Refactor LocalCache to use PubSub for change token signals Replaced direct event stream usage with PubSub in LocalCache implementation. Updated service and hosted service to support PubSub subscription and publishing. Removed obsolete Start and Stop RPC methods from LocalCache service definition. * Add UsedImplicitly attribute to notification handler This change introduces the [UsedImplicitly] attribute to the DistributedWorkflowDefinitionNotificationsHandler class. The attribute is intended to prevent any accidental removal by static analysis tools, ensuring the class remains available for dynamic usage scenarios. * Refactor caching and signal handling mechanisms Replaced `TriggerChangeTokenSignalConsumer` with `ChangeTokenSignalInvoker` and added new decorators for change token handling. Renamed namespaces and file paths for better consistency and clarity. Updated test files to align with these changes. * Remove unnecessary interface dependencies from services Eliminated the ISignalManager and related interfaces to streamline dependency management. Updated services and test components to use concrete implementations directly, reducing complexity and improving maintainability. * Remove Shared.proto and associated imports Deleted the Shared.proto file and removed related import statements across multiple files. This cleanup also involved modifying the proto actor provider and project file to exclude references to Shared.proto. * Simplify namespaces in component test helpers Consolidated several namespaces into 'Elsa.Workflows.ComponentTests.Helpers' to reduce redundancy and improve maintainability. Removed unnecessary using directives in multiple test files for cleaner and more readable code. * Refactor imports in component tests Consolidated various helper imports in component tests by removing redundant specific references and utilizing general 'Elsa.Workflows.ComponentTests.Helpers'. This change simplifies the dependency management and ensures cleaner and more maintainable code. * Remove redundant state persistence calls Eliminated multiple calls to PersistStateAsync in WorkflowInstanceImpl.cs as they were unnecessary given that the WorkflowRunner already invokes the commit handler. This change simplifies the workflow execution and cancellation logic by avoiding redundant state persistence operations. * Add workflowInstanceId to response mapping Updated methods to include workflowInstanceId in response mapping functions for consistency and clarity. Additionally, fixed project reference paths and added error handling for missing workflow variables in tests. * Remove unnecessary variable existence check Removed a redundant check for the existence of the "Workflow1:variable-1" key in the variables dictionary. This streamlines the test and relies on the assumption that the key exists as expected without explicit validation. * Add Kubernetes deployment and service configurations Introduced a Deployment and Service configuration for the Kubernetes cluster. Updated Dockerfiles and build script to align with port 8080 configuration and renamed images for consistency. Updated solution file to include new deployment files. * Add Kubernetes cluster integration Introduced Kubernetes cluster provider for Proto.Actor and configured the application to use it if running in a Kubernetes environment. Added necessary RBAC roles, role bindings, and service accounts to support Kubernetes integration. Updated deployment configuration and package references to include Proto.Cluster.Kubernetes. * Refactor deployment configurations and add service support. Reorganized deployment YAML files into designated subdirectories for elsa-server, postgres, plant-uml, and trace-lens. Introduced new configuration maps, service accounts, roles, and service bindings. Updated .NET environment variables and solution structure to reflect these changes. * Update service configurations and environment variables Renamed and split services in trace-lens to isolate the OTEL collector. Updated environment variables in elsa-server to enhance instrumentation, connection strings, and profiling settings. Adjusted OTEL exporter endpoint to match the new service naming. * Increase deployment replicas to 3 Updated the 'replicas' field in the deployment configuration to enhance the system's availability and load balancing. This change ensures that three instances of 'elsa-server' will be running simultaneously. * Rename LocalCacheImpl to LocalCache and add logging Renamed `LocalCacheImpl` class to `LocalCache` to better reflect its purpose. Added a logging statement in `OnReceive` method to log incoming `ProtoTriggerChangeTokenSignal` messages. These changes improve code readability and debugging. * Disable OTEL console exporters and set session affinity Disabled console exporters for logs, metrics, and traces in the OTEL configuration to reduce unnecessary console output. Additionally, set session affinity to 'None' in the elsa-server service configuration for load balancing. * Rename WorkflowInstanceImpl to WorkflowInstance Updated the class name from WorkflowInstanceImpl to WorkflowInstance for clarity and simplicity. Adjusted all relevant references and instances in the codebase to match the new class name. * Remove ActivityIncidentStateMapper and Update ProtoBuf Mappings Removed the unused ActivityIncidentStateMapper class to streamline the codebase. Updated all related ProtoBuf mappings and imports to ensure consistency and remove redundancy across the project. * Remove duplicate actor spawn verification timeout setting The code had a redundant setting for actor spawn verification timeout, which was specified twice. This commit removes the duplicate line to ensure cleaner and more maintainable configuration. * Remove unused imports from Program.cs Eliminated unnecessary imports for ActivityExecution, WorkflowExecution, and k8s libraries. This cleanup helps reduce the code footprint and may improve compile time. * Remove debug logging from LocalCache actor The `Console.WriteLine` statement was removed from the `OnReceive` method in `LocalCache.cs`. This change eliminates unnecessary console output during the token signal handling, improving performance and reducing log clutter. 2024-07-24 20:23:33 +00:00			`namespace Elsa.Caching.Distributed.ProtoActor;`
