When should I use Amazon RDS instead of Databricks?

Managed relational database hosting (MySQL, PostgreSQL, SQL Server, Oracle) on AWS. Teams who want automated backups, failover, patching, and scaling without DBA overhead. Production OLTP databases in the AWS ecosystem needing high availability with Multi-AZ deployment

When should I use Databricks instead of Amazon RDS?

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

What are the main weaknesses of Amazon RDS?

More expensive than self-managed EC2 database instances for the same database workload. Limited OS-level and advanced configuration access compared to self-managed databases. Aurora is often preferred over standard RDS for performance-critical or high-scale workloads

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

How Python Data Engineers Use These Tools

Amazon RDS

Python data engineers use RDS as the managed database backend for pipeline metadata stores, staging databases, and application databases. Engineers connect via standard Python database drivers (psycopg2, pymysql) or SQLAlchemy, using IAM authentication for credential-free access. RDS Proxy is used in Lambda-based ingestion functions to avoid connection pool exhaustion.

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.
