Thank you for your thoughtful comment and suggestion! You've raised an excellent point about optimizing cost when iterating over objects in an S3 bucket.

Using S3 Inventory reports can be a more cost-effective and scalable approach to searching for text within files stored in large S3 buckets, particularly for non-time-sensitive searches. It reduces the direct API call costs associated with listing objects and can make the overall search process more efficient by narrowing down the list of files to be examined. However, it introduces a delay due to the inventory generation schedule and requires additional setup and processing steps. The best approach depends on your specific needs, including how up-to-date your search results need to be and the balance you wish to strike between cost, efficiency, and timeliness.

Thankyou :)
