Navigating the No-SQL Labyrinth: DynamoDB, Cassandra, MongoDB and Redis | by Tomer Ben David | Medium
March 13, 2024 - This provides a good balance between performance and data organization. However, setting up Cassandra clusters can be more complex compared to DynamoDB’s managed service approach. Imagine Cassandra as a seasoned veteran — strong, reliable, but requiring some upfront investment in strategy. ... MongoDB entered the scene as a breath of fresh air.

March 31, 2026 - Compared to DynamoDB, ScyllaDB achieves 40x lower cost, 4x better latency, and single-digital ms latencies with no external cache. Compared to MongoDB, ScyllaDB achieves 20x higher throughput, 68x lower P99 latencies, 19x better price-performance.
MongoDB versus DynamoDB
MongoDB (or DocumentDB, for that matter) is focused on documents. DynamoDB (or Cassandra) is focused on key:value pairs. While you could potentially use either for multiple applications, depending on your use case one or the other may be a better fit. DynamoDB is used quite commonly for a lot of companies - Uber, Lyft, Tinder, Capital One, etc. If you want to learn more about DynamoDB design patterns, this is a fantastic video from a re:Invent session - very dense and engineering focused. https://www.youtube.com/watch?v=HaEPXoXVf2k More on reddit.com

July 26, 2024Why is Cassandra considered column-based and DynamoDB key-value?
Cassandra and DynamoDB are both: https://en.wikipedia.org/wiki/Wide-column_store . I think it's a bad name, since it creates confusion with "column stores", i.e. https://en.wikipedia.org/wiki/Column-oriented_DBMS , which are not related. I think some confusion comes because in the original Dynamo paper https://www.allthingsdistributed.com/files/amazon-dynamo-sosp2007.pdf it is only a key-value store. But DynamoDB (the AWS offering) is not the same thing as Dynamo the paper. Also remember, just about any database is a key-value store. MySQL fulfills the criteria of a key value store. So does Cassandra. AWS itself describes DynamoDB as a "document store", but that's bad too. They're referencing that it doesn't enforce a schema (which *is* a key difference from Cassandra). However, I think it misses the capability of arbitrary indexes within the document, which is something that Mongo and XML databases do. More on reddit.com

August 21, 2021When would you NOT choose DynamoDB where you'd typically use RDBMS?
I prefer rdmbs when query patterns aren't known ahead of time, when there's lots of relationships between data, and when update patterns of that data would make it cumbersome to maintain denormalized updates in something like dynamo or Cassandra. Big table style databases are great if your data relationships are simple and all well known ahead of data modeling time. Trying to map an rdbms mentality to data modeling in a big table style database will make for a world of hurt. More on reddit.com

April 25, 2024 - DynamoDB performs a number of tasks for its users, including all security activities. As part of the AWS cosmos and the IAM model (Identity and Access Management), the database is well protected and embedded. There is no direct connection to the internet, as requests are first routed through an API gateway. Compared to DynamoDB, the workload when using MongoDB is significantly higher if you want to ensure the security of your database.

September 11, 2025 - The platform delivers consistent single-digit millisecond latency for items under 4 kilobytes, with the DynamoDB Accelerator (DAX) providing microsecond-level caching capabilities for frequently accessed data. Schema design, document structure, and index usage heavily influence performance. Poorly chosen sharding keys or deeply nested documents can slow queries. MongoDB 8.0's performance improvements include reduced majority-write latency via parallel journaling and regression testing that automatically detects micro-optimization losses.
