I need to develop a real-time CDC log-based product that extracts incremental data from an AS/400 system and stores it in AWS S3. The extracted data should be stored in JSON format. No transformations are needed during the extraction process; instead, all transformations will be performed after the data is stored in S3. Additionally, there is no need for partitioning the stored data on S3. The system should be efficient, reliable, and capable of handling real-time data synchronization from AS/400 to AWS S3. Please ensure compatibility with the mentioned systems and provide a clear approach to achieving the above requirements.
