S3 Upload Management and Flush Options

Description

Enhance S3 upload management with configurable flush strategies and atomic file operations to ensure data consistency and optimal performance.

Tasks

• Implement configurable flush strategies based on:
  • Record count ()
  • Time-based intervals ()
  • File size thresholds
• Add support for atomic file operations to prevent partial uploads
• Implement proper error handling and retries for S3 operations
• Add backpressure mechanisms for memory management
• Support configurable S3 client options (region, credentials, endpoints)
• Implement efficient buffering strategies to minimize memory usage

Technical Details

• Use the Rust AWS SDK for S3 operations
• Implement memory-efficient buffering to outperform Java implementation
• Add metrics for monitoring flush operations and performance
• Support both synchronous and asynchronous flush modes
• Implement proper cleanup of temporary files

Acceptance Criteria

• All flush strategies work correctly and respect configured thresholds
• S3 uploads are atomic and consistent
• Performance exceeds Java implementation
• Memory usage remains low even with large record batches
• All tests pass including edge cases like network failures

Priority

High (Priority 3 in GAP analysis)
