So all writes are written directly to S3? Are you putting each write into
a separate object? I've been doing some research into using S3 as a
general purpose data store which lead me to mnesia and erlang. It seems
to me that the limiting factor is the transactional costs per write.
I thought not being able to do record appends was a real deal killer for
more structured data stores, but it sounds like you've figured out some
way around this.
I'd love to hear more about this.
