S3 Express Append has issues

AWS is clearly gearing up to make S3 Express a potential alternative to EBS disks. Like EBS, S3 Express is single zone. Earlier this year, AWS added the conditional write primitive to both S3 and S3 Express. Now it has released the ability to append to objects in S3 Express.

As a potential thought bubble, for append to behave like EBS in S3 Express, AWS needs to introduce some form of per-prefix (short term) leases with queues. You still get charged the price of a PUT call, meaning any potential benefits must come from reduced code complexity or savings in compute resources needed to combine objects in memory. S3 express itself imposes a limit of 10,000 appends per object, which may not suffice for systems where the size threshold for transferring data to standard S3 is higher.
