Why wouldn't it be "fair"?
- dullgiulio 9y agoBecause a key-value store is a foundamentally simpler data structure (it's an hash) than a relational database, which tracks the relations between different data types. If you make an advanced use of the key-value store, you have a lot of logic in the application (for example to key management, cascade operations between related data...) which a relational database should do for you. It's not fair because there is a development cost in using the key-value you are ignoring.
- ubernetes 9y agoDynamo is not a k-v store.
- vira28 9y agoApart from the points @dullgiulio mentioned. DDB -> NoSQL, No Automatic backups, No support for ad-hoc querying, eventual consistency (though you can set to get consistency with few tradeoffs) Spanner DB -> RDBMS, Automatic backups, Enriched SQL, Strong consistency. Let me if you still think its fair to compare these 2 databases.
