DynamoDB Integration

[dheerajoruganty]

Description

This PR delivers end-to-end functionality to integrate DynamoDB into the FMBench Orchestrator, enabling persistent logging of run data directly within a DynamoDB table. From initial setup to full integration, the orchestrator now logs each run in a structured, persistent, and queryable format, ensuring data retention and traceability.

Summary of Changes

• DynamoDB Table Creation and Management:
  • Introduced the get_or_create_table method, which checks for an existing DynamoDB table or creates a new one if absent.
  • Configured the table with a composite primary key, using run_uid as the partition key and timestamp as the sort key, allowing multiple entries per run_uid to capture each run's stages and updates over time.
  • Enabled PAY_PER_REQUEST billing to handle varying workloads without pre-set capacity.

Testing and Validation

• Functional Testing: Validated the DynamoDB table creation and retrieval under various scenarios, including successful retrieval of an existing table, creating a new table, and handling IAM permission errors gracefully.
• Integration Testing: Confirmed that FMBench can log runs with run_uid and timestamp values, successfully writing data to DynamoDB
