With the current implementation; no problems hitting the limit. As mentioned in my below comment, our query for anonymization would be the heaviest - but it's designed to be quick as we don't care about unique values for most data.

If we did though - Fargate is a great solution for it, but you wouldn't be able to feed data back into the next step without some additional complexity - Maybe have the next step pull an SQS queue, or an S3 file, or look for a database entry, etc. as it's next bit of data that it needs - and just fail until it finds it, and once the Fargate (Or whatever) has done it's job and placed it in your method of choice, then it could continue.
