The DynamoDB model has several key benefits over Cassandra's.
The most notable one is the tablet concept - data is partitioned into 10GB

Expansion probably much faster in 4.0 with complete sstable streaming
(skips ser/deser), though that may have diminishing returns with vnodes
unless you're using LCS.
Dynamo on demand / autoscaling isn't magic - they're overprovisioning to
give you the burst, then expanding on demand. That
Out of curiosity, does DynamoDB autoscaling allows you to exceed the
partition limits (e.g. push more data than it is allowed for some outlier
heavy partitions) ? If yes, it can be interesting (I guess DynamoDB is
doing some kind of rebalancing behind the scene). If no, it's just an
artificial
Dynamo salespeople have been pushing autoscaling abilities that have been
one of the key temptations to our management to switch off of cassandra.
Has anyone done any numbers on how well dynamo will autoscale demand
spikes, and how we could architect cassandra to compete with such abilities?
We
