Option A - the 'turn it on and forget it' approach. Way better than option D, the 'make up config settings as you go' approach.

Hadoop.s3.consistency = true? That's a new one to me. I'd stick with the tried and true option A.

Setting Hadoop.data.consistency = true might work, but I'm not sure if that applies specifically to S3 data. Option A is probably safer.

AWS Data Pipeline could work, but that adds an extra layer of complexity. I'd go with the simpler option A.

Option A seems like the most straightforward approach. Consistent view should help ensure the reads in subsequent cycles see the latest data.
