Best NoSQL Databases to Use in 2025

Which NoSQL databases lead the pack in 2025?

What Are the Best NoSQL Databases in 2025?

MongoDB Atlas, Amazon DynamoDB, Google Cloud Firestore, Couchbase Capella, Redis Enterprise Cloud, DataStax Astra DB, Microsoft Azure Cosmos DB, Fauna, ArangoDB Oasis, and Apache HBase on CDP top our 2025 leaderboard.

Each shines in distinct workload patterns—from globally distributed document storage to sub-millisecond in-memory key-value access.

How Did We Rank These NoSQL Databases?

We scored products on seven dimensions: feature breadth, scalability, ease of use, ecosystem integrations, performance benchmarks, pricing transparency, and support. Public SLAs, TPC-x benchmarks, and verified customer reviews informed weightings. The highest composite scores determine ranking.

Is MongoDB Atlas Still the Document DB to Beat?

MongoDB Atlas keeps the No.

1 spot by merging flexible JSON documents with auto-sharding, multi-region clusters, and an expanding Aggregation Pipeline. In 2025, Atlas Serverless adds usage-based billing that scales to zero, while Queryable Encryption enables client-side encrypted search without schema trade-offs.

Why Do Teams Choose Amazon DynamoDB for Serverless Scale?

DynamoDB delivers single-digit-millisecond reads at any scale. On-demand capacity, PartiQL SQL-like queries, and integrated global tables make it a go-to for event-driven microservices.

Recent 2025 updates include Incremental Export to S3 and vector search preview for GenAI indexing.

Where Does Google Cloud Firestore Excel?

Firestore seamlessly syncs data to web, iOS, and Android clients with offline caching. Its hierarchical document model and real-time listeners simplify chat, IoT, and collaborative editing apps. The 2025 regional-plus tier cuts tail-latency by 30 percent, while new composite index insights auto-optimize queries.

Who Should Consider Couchbase Capella?

Capella blends key-value, document, and SQL++ query support.

Adaptive compression and zero-touch autoscaling slash TCO for e-commerce catalogs and session stores. Capella iQ, a built-in AI assistant released in 2025, generates SQL++ from natural language, speeding analytics.

When Is Redis Enterprise Cloud the Right Pick?

Sub-millisecond latency and built-in data structures keep Redis Enterprise atop caching and real-time leaderboard use cases.

New Redis 7.4 modules add vector similarity search and durable tiered memory, letting teams run GenAI and time-series workloads without switching engines.

How Does DataStax Astra DB Modernize Apache Cassandra?

Astra DB offers a serverless Cassandra-compatible API, plus JSON, GraphQL, and gRPC endpoints.

Vector search and Retrieval Augmented Generation (RAG) pipelines debuted in 2025, positioning Astra as a high-throughput foundation for AI assistants needing globally distributed context stores.

What Makes Azure Cosmos DB Unique?

Cosmos DB provides multiple wire-compatible APIs—MongoDB, Cassandra, Gremlin, Table, and Core SQL. Its 99.999 percent SLA covers latency, availability, consistency, and throughput.

2025’s burst capacity and hierarchical partition keys improve cost efficiency for unpredictable IoT telemetry.

Should You Try Fauna for Global ACID?

Fauna is a document-relational database with strong consistency and a pay-as-you-go model. Real-time streaming and temporal queries suit fintech ledgers. The 2025 Data Residency feature locks data to regulatory regions without manual shard management.

Where Does ArangoDB Oasis Fit?

ArangoDB’s multi-model engine combines documents, graphs, and key-value in one cluster.

SmartGraphs and Pregel parallel graph analytics tackle recommendation systems. Oasis 2025 now offers autopilot scaling and a WASM-based query engine that halves CPU costs.

Is HBase on Cloudera Data Platform Still Relevant?

HBase remains a staple for write-heavy time-series at petabyte scale. CDP 2025 introduces auto-bucket cache resizing and zero-downtime upgrades, narrowing the ops gap with cloud-native rivals while retaining Hadoop ecosystem integration.

Which NoSQL Engine Is Cheapest in 2025?

Cost varies by workload.

DynamoDB and Cosmos DB charge per request unit, ideal for spiky traffic. Atlas and Capella offer cluster and serverless modes. Redis Enterprise’s tiered memory lowers costs for large datasets. Evaluate total query volume, storage, and replication before choosing.

Can One NoSQL Database Cover Every Use Case?

No single engine optimizes all access patterns. Combine databases—Redis for caching, DynamoDB for key-value, and Snowflake for analytics—using change-data-capture pipelines.

Polyglot persistence minimizes compromise.

What Are Best Practices for Migrating to NoSQL?

Start with a bounded context. Model access patterns before schemas. Use automated data migration tools (e.g., Atlas Live Migrate, DynamoDB DMS). Validate performance with production-like traffic and enforce observability from day one.

How Does Galaxy Complement NoSQL Workflows?

Most NoSQL deployments still pipe data into SQL analytics lakes.

Galaxy’s lightning-fast SQL editor and AI copilot let engineers explore DynamoDB streams or Atlas Data Federation via federated SQL, share vetted queries, and automate transformations—filling the last-mile gap between NoSQL and insights.

Key Takeaways

Choose MongoDB Atlas for flexible document workloads, DynamoDB for hyperscale key-value, and Firestore for mobile sync. Match engine strengths to access patterns, layer in Galaxy for collaborative SQL on top, and you’ll future-proof your 2025 data stack.
