Hi Gowthamprabhu,
How many records do you have that require cleansing? I usually try to stay under 10,000 records not just for the S3 file cleanser but for other services that accept files such as external match and try to use these services in iteration on batches of 10,000 records. It is easier to manage the output and share it with any downstream system for further processing.
