The DynamoDB model has several key benefits over Cassandra's.
The most notable one is the tablet concept - data is partitioned into 10GB
chunks. So scaling happens where such a tablet reaches maximum capacit

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
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

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?

Hi,
Autoscaling is not possible with a Cassandra cluster. Any topology change
triggers series of streaming and data shuffle around the cluster. Scaling
the cluster up or down is an operational challenge which is usually planned
in production because of the performance impact it can make.

Hi,
I am using Cassandra 3 with a single DC. I would like to know if there is
any tool available for scaling up and down Cassandra automatically.
Thanks
Netflix uses Scryer

Hello Prem,
I'm trying to find out whether people are autoscaling up and down
automatically, not manually. I'm also interested in whether they are using
a cloud based solution and creating and destroying instances.

I'd be interested to know whether people out there are autoscaling
cassandra on demand.
