Workload Requirements

Multi-row ACID Transactions3

Strict financial or inventory transactions requiring rollbacks across multiple tables.

Joins & Reporting3

Heavy analytical ad-hoc queries, Group Bys, and normalized schema structures.

Extreme volume of GET requests looking up single keys or session states.

Flexible Schema / Document3

Unstructured or rapidly changing schemas where you don't want to run ALTER TABLE.

Full-text Search3

Fuzzy matching, relevance scoring, and typo tolerance for search bars.

Vector Similarity / AI3

RAG architectures, semantic search, and nearest-neighbor vector embeddings.

Global Scale / Distributed3

Need the database to seamlessly partition and scale across multiple geographical regions.

Operational Simplicity3

Desire for a managed, serverless, or zero-maintenance architecture.
