Apache CouchDB

Protocolo de Datos Descentralizado

An open-source NoSQL document database with an HTTP/JSON API, built for reliability and for multi-primary sync that scales from large clusters down to mobile and browser clients. Any CouchDB database, on a server or a device, can replicate with any other over the documented CouchDB Replication Protocol, which synchronises JSON documents between two peers over HTTP/1.1 using the public REST API and the project's multi-version concurrency control (MVCC) model; conflicting edits are detected through revision trees rather than merged automatically. CouchDB is the reference implementation of that protocol, which PouchDB and other tools reuse. It is a project of the Apache Software Foundation .

Protocolo de Datos Descentralizado Atributos

Orígenes A reliable, always-available document database that can be replicated between servers and, increasingly, mobile and browser clients, with a plain HTTP/JSON interface any language can use
Base de Datos CouchDB: this entry is the database. A document store with MVCC revision trees and, in the 3.x series, clustering (the documentation has a Cluster Management guide)
Lenguaje de Consulta HTTP/JSON API; Mango selector queries and map/reduce views (the documentation has a Query Server and API reference)
Formatos de Datos JSON documents with revision identifiers and binary attachments; JSON over HTTP
Edición Colaborativa en Vivo Partial: documents replicate between peers and conflicting edits are surfaced as revision conflicts for the application or the deterministic winner rule to resolve; there is no automatic character-level merge
Edición de Texto Enriquecido Not stated by the project.
Soporte Móvil Through sync: the home page says CouchDB scales down to mobile; PouchDB and other clients provide the on-device database
Soporte Web Yes: the Fauxton web console and an HTTP/JSON API usable directly from browsers
Aplicaciones Nativas Server packages for Windows, macOS and Linux; no native client library of its own
Términos Free and open source (Apache-2.0)
Fondos Not stated by the project.
Basado En Its own MVCC and replication model; the replication protocol is the shared standard that PouchDB and other tools implement
Arquitectura P2P Peer-to-peer replication between servers and clients: any two CouchDB databases (or compatible stores) replicate with each other over HTTP, in either direction or both, without a coordinator; the project presents this as multi-primary sync. It is not an overlay network, and discovery is manual
Red de Superposición None: replication endpoints are addressed by URL; the cluster mode is a data-centre feature, not an overlay
Direccionamiento por Contenido No: documents are addressed by identifier and revision (revision ids are hashes of content), not by content hash
Local-First Enabling: the replication model underpins local-first clients such as PouchDB; the server itself is a conventional database that can run anywhere, including on a user's own hardware
Cifrado de Extremo a Extremo (E2EE) No: the database stores documents as submitted; transport security is TLS and encryption at rest is left to the platform
Biblioteca de CRDTs No: conflicts are tracked with revision trees rather than CRDTs
Tolerancia a Fallos Bizantinos No: replication trusts the authenticated peer; the project designs for crash and partition tolerance, not malicious replicas
Firma N/A: documents are not signed; authentication is cookie, basic or proxy-based on the server
Permisos Server-side: per-database admin and member roles with validate_doc_update functions; no end-to-end document permissions
Compatibilidad con la Web Semántica N/A: JSON document store with no RDF layer
Contrato Inteligente N/A: no ledger or contract component
Posición en la Pila del Protocolo Application-layer: HTTP/1.1 REST API and replication protocol
Incorporación de Activos/Valor None: no token or value-transfer mechanism
Madurez del Protocolo / Estandarización Mature: the CouchDB Replication Protocol is written down as a normative specification using RFC 2119 language and is implemented by several independent projects, though it is an ASF project specification rather than an IETF or W3C standard
