When should I use Couchbase instead of Amazon DynamoDB?

Mobile data sync and offline-first applications using Couchbase Lite on iOS and Android. JSON document store with N1QL SQL-like query language for flexible, schema-optional data models. High-availability key-value and document access with sub-millisecond read latency

When should I use Amazon DynamoDB instead of Couchbase?

Serverless key-value and document store with single-digit millisecond latency at any scale on AWS. AWS-native applications needing elastic scaling without upfront capacity planning. Gaming leaderboards, session stores, and e-commerce carts needing consistent low-latency access

What are the main weaknesses of Couchbase?

Full enterprise features require a commercial license; Community Edition is significantly limited. N1QL query performance depends heavily on correct index design for each access pattern. Smaller community than MongoDB for general document store use cases

What are the main weaknesses of Amazon DynamoDB?

Data modeling is complex — access patterns must be known upfront for efficient partition key design. Expensive for read-heavy analytical workloads; full table scans are slow and costly. No joins or ad-hoc SQL; analytical queries require DynamoDB Streams plus Redshift or Athena

How Python Data Engineers Use These Tools

Couchbase

Python data engineers use the `couchbase` SDK to store and retrieve JSON documents representing pipeline entities — user profiles, product catalogs, or session data. N1QL lets engineers run SQL-like analytical queries from Python without schema migrations, and the full-text search integration enriches ingested documents with relevance-scored lookup capabilities.

Amazon DynamoDB

Python data engineers use `boto3`'s DynamoDB resource to store pipeline state, idempotency tokens, and metadata that needs sub-millisecond lookup by key. DynamoDB Streams connected to Lambda functions enable event-driven pipeline triggers — each new record insert automatically kicks off downstream processing without polling.
