Create a scheduler job to check on pending documents (EventType - RedactionStatusPending) and trigger the Return Result API (Step 5).

• Use EventBridge to trigger new lambda which invokes the integration API to reprocess documents (Checks for Status - EventType.RedactionStatusPending).

Research Info on Scheduler Jobs:

1. http://Quartz.NET :

   • Description: Quartz NET is a powerful, open-source job scheduling library for .NET applications.

   • AWS Integration:

     • Manual Setup: You can deploy http://Quartz.NET on AWS infrastructure (e.g., EC2 instances) and configure it to run scheduled tasks.

     • Database: If you use http://Quartz.NET with a database (e.g., PostgreSQL on Amazon RDS), you’ll need to manage the database setup and maintenance.

     • Complexity: Requires manual setup and maintenance.

   • Use Cases:

     • Suitable for applications that require advanced scheduling features beyond what AWS provides out of the box.

     • Useful when you need fine-grained control over scheduling logic.

     • Can be used for distributed jobs (with clustering).

   • Example: You might use http://Quartz.NET for complex workflows or tasks that involve intricate scheduling rules.

2. Amazon EventBridge Scheduler:

   • Description: EventBridge Scheduler is a serverless scheduler provided by Amazon EventBridge.

   • Serverless and Managed: EventBridge Scheduler is fully managed by AWS, which means you don’t need to set up or maintain any infrastructure.

   • Scheduling Options:

     • Cron Expressions: EventBridge Scheduler supports cron expressions for recurring patterns.

     • Rate Expressions: Allows simpler schedules (e.g., every 5 minutes).

   • Integration:

     • Event-Driven: EventBridge Scheduler is part of the broader EventBridge service, which allows you to build event-driven architectures.

     • Targets: You can easily configure targets (e.g., SQS, SNS, AWS Lambda functions) for scheduled events.

   • Use Cases:

     • Ideal for serverless tasks that need to run on a schedule.

     • Efficient for lightweight scheduling needs.

     • Simplifies event-driven workflows.

   • Example: You might use EventBridge Scheduler to trigger an AWS Lambda function periodically or perform other time-based actions.

• Check the audit table - CoralRedactionIntegrationLog for Pending Status EventType.Status - RedactionStatusPending

• Get the CorralationId and invoke Integration API to Download result.

• Update the status on the Audit table with response - Complete/Error.

• Invoke Backend API SaveAutoRedaction with response.
