When should I use Amazon DynamoDB instead of Titan?

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

When should I use Titan instead of Amazon DynamoDB?

Large-scale distributed graph database backed by Cassandra or HBase for massive graph workloads. Graph workloads at petabyte scale requiring horizontal sharding across distributed storage. Legacy graph projects in the Hadoop ecosystem that predated modern managed graph services

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

What are the main weaknesses of Titan?

Project is archived and no longer maintained; JanusGraph is the official community successor. Very complex to deploy and operate correctly alongside Cassandra or HBase. Not recommended for any new project — use JanusGraph or Neo4j instead

How Python Data Engineers Use These Tools

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.

Titan

Python data engineers use Titan (now superseded by JanusGraph) with the `gremlin-python` driver to traverse large graph datasets stored in Cassandra or HBase. Gremlin traversal queries find multi-hop relationships in fraud detection, recommendation, and knowledge graph pipelines — the Python Gremlin driver sends queries to the Titan/JanusGraph server and processes results as Python dicts.
