FaunaDB

FaunaDB is a distributed document-relational database provided as a cloud API. It combines the capabilities of a document-oriented data model with the querying features of a relational database. According to the vendor, FaunaDB offers a reliable and scalable database solution suitable for businesses of all sizes. It caters to software developers, database administrators, DevOps engineers, e-commerce companies, and financial services institutions.

Key Features

Distributed transaction engine: FaunaDB's distributed transaction engine, tested by Jepsen, ensures strong consistency across geographically dispersed regions. It allows for distributed reads and writes with low latency, providing high availability without any single points of failure.

Fully serverless database: FaunaDB is a serverless database that manages all database management tasks, including hardware, integration, and operational tasks. It seamlessly integrates with existing developer workflows, enabling developers to focus on application development.

TypeScript-inspired database language (FQL): FaunaDB uses the Fauna Query Language (FQL), a strongly-typed database language inspired by TypeScript. FQL enables developers to express queries and functional business logic in transactions that are strongly consistent across multiple regions.

Multi-region database with 1-click setup: FaunaDB allows users to set up a multi-region database with just a single click. Users can select a Fauna Region Group and create a new database with automatic replication across three regions, ensuring data availability and proximity to users or devices.

JSON document model with flexible schema: FaunaDB employs a JSON document model, offering flexibility and adaptability during early application development. Its flexible schema support allows users to add structure to their data over time, facilitating the evolution of data models and applications.

Relational power with declarative queries: FaunaDB provides powerful querying capabilities with declarative queries. Developers can efficiently transform query results and navigate relationships, leveraging robust filtering and joining capabilities without custom join logic in application code.

ACID consistency for multi-region deployments: FaunaDB ensures strict ACID guarantees within transactions, even in multi-region deployments. This level of consistency ensures data accuracy and transactional integrity, making FaunaDB suitable for mission-critical applications.
