Apache CouchDB
Apache CouchDB is an open-source distributed document-oriented NoSQL database governed by the Apache Software Foundation. It uses JSON for data storage, a RESTful HTTP/JSON API for all database operations, and the Couch Replication Protocol for multi-primary synchronization across servers, mobile devices, and browsers. CouchDB supports Mango queries, MapReduce views, and offline-first application architectures.
Apache CouchDB publishes 9 APIs on the APIs.io network, including Authentication API, Changes API, Cluster API, and 6 more. Tagged areas include Apache, Database, Document Store, JSON, and NoSQL.
The Apache CouchDB catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 3 Spectral governance rulesets.
Apache CouchDB’s developer surface includes authentication, developer portal, documentation, getting-started guide, engineering blog, release notes, support, and 9 more developer resources.

FINOPSFeatures 8
Notable capabilities this provider offers.
RESTful HTTP/JSON API
All database operations are performed via a clean HTTP API using JSON, making it accessible from any HTTP-capable client.
Multi-Primary Replication
The Couch Replication Protocol enables seamless bidirectional synchronization across servers, mobile, and browser environments.
Offline-First Architecture
Applications can operate fully offline and sync changes when connectivity is restored, enabled by conflict-aware replication.
Mango Query Language
Declarative JSON-based query language for ad-hoc document queries with index support, similar to MongoDB query syntax.
MapReduce Views
Persistent, incrementally updated secondary indexes defined via JavaScript MapReduce functions stored as design documents.
Changes Feed
Real-time notification feed of all database changes, supporting long-polling, continuous, and event-source modes.
Cluster Support
Built-in clustering with consistent hashing for horizontal scaling and high availability across multiple nodes.
MVCC and ACID
Multi-Version Concurrency Control ensures non-blocking reads; document updates are ACID-compliant at the document level.
