What were your considerations when deciding between API BaaS, DynamoDB, and Cassandra?

[#1]

In the article API BaaS, DynamoDB, and Cassandra - which should I use? I’ve shared how that economics, complexity, developer focus, support, and agility are the criteria.

Have you had the same experience? In what use cases you would choose one technology over the other ones?

I have seen following criteria playing an important role.

1. performance
2. ease of accessing the records (including different ways of access)
3. scalability
4. distributed transaction support
