Does S3 Strong Consistency mean disabling EMRFS Consistent Views?

0

Customer is using EMR FS consistent view because S3 was eventually consistent. Post-Re:Invent 2020, with Amazon S3 Strong Consistency, they no longer need EMR FS Consistent View. Can customer start disabling EMR FS consistent view for their clusters? Any other changes/settings we can share with customers to be aware of?

As Jeff Barr mentions in his blog post that EMRFS Consistent Views is not longer needed , and so I think it is safe to advise the customer they can disable it.

No other changes/setting would be impacted. EMRFS it is obviously still needed.

Here's the documentation on S3 consistency, which includes reads after deletes ( a delete is a type of write)

Amazon S3 data consistency model Amazon S3 provides strong read-after-write consistency for PUTs and DELETEs of objects in your Amazon S3 bucket in all AWS Regions. This applies to both writes to new objects as well as PUTs that overwrite existing objects and DELETEs.
