When should I use Databricks instead of Amazon DynamoDB?

Unified data and AI platform for large-scale Spark workloads, Delta Lake, and ML in one environment. Delta Lakehouse architecture combining data warehouse and data lake capabilities on object storage. Teams running ETL, ML training, and SQL analytics on a single managed, auto-scaling platform

When should I use Amazon DynamoDB instead of Databricks?

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 Databricks?

Expensive at scale — compute and DBU costs grow quickly for large teams and heavy workloads. Vendor-managed Spark adds abstraction; debugging cluster behavior and tuning is harder. Some Delta Lake features have no open-source equivalent outside the Databricks Runtime

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

Databricks

Python data engineers use Databricks notebooks and jobs to run PySpark ETL pipelines on Delta Lake. Engineers write Python and SQL in notebooks, schedule jobs via the Databricks Jobs API or Airflow, and use the Databricks Connect client to run Spark commands from local IDEs. MLflow auto-logging captures experiment metrics without any extra code.

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.
