Se puede utilizar de forma inteligente para enlazar clientes sin ning\u00fan back-end, por ejemplo.  En una\u00a0<a style=\"color: #1b8be0;font-style: inherit;font-weight: inherit;line-height: 1.625;text-decoration: none\" href=\"https:\/\/www.couchbase.com\/blog\/es\/couchbase-mobile-v1.3-openid-connect\/\">entrada anterior<\/a>ya habl\u00e9 de la compatibilidad con OpenID Connect.  Sync Gateway act\u00faa all\u00ed para facilitar todo el flujo de autorizaci\u00f3n.  Hay m\u00e1s, pero en este post quiero centrarme en una nueva capacidad a\u00f1adida en la versi\u00f3n 1.3.<\/p>\n<h2 style=\"font-size: 15px\">Una mirada m\u00e1s profunda a la sincronizaci\u00f3n<\/h2>\n<p style=\"color: #333333;font-size: 15px\">La sincronizaci\u00f3n consiste en mantener la coherencia de los datos en dos o m\u00e1s instancias de una base de datos.  La sincronizaci\u00f3n puede ser un problema dif\u00edcil.  Cada vez que dos escritores intentan hacer cambios contradictorios, la arquitectura tiene que lidiar con ello.<\/p>\n<p style=\"color: #333333;font-size: 15px\">Algunas bases de datos simplemente ignoran el problema, obligando a utilizar un \u00fanico escritor.  Otras dependen de la detecci\u00f3n de conflictos en tiempo real y su rechazo.  Estos enfoques no funcionan en los casos en que distintas copias de la base de datos no siempre pueden comunicarse para coordinarse.<\/p>\n<p style=\"color: #333333;font-size: 15px\">Una buena arquitectura de sincronizaci\u00f3n es un componente cr\u00edtico de una soluci\u00f3n completa que aborda usos en los que un dispositivo puede estar en una conexi\u00f3n de red lenta, o estar desconectado por completo parte del tiempo.  Sync Gateway implementa una pieza central de esa arquitectura en Couchbase.<\/p>\n<p style=\"color: #333333;font-size: 15px\">Nos referimos a la pila completa como Couchbase Mobile.  Los usos m\u00f3viles son un caso obvio donde el rendimiento offline puede ser importante.  Sin embargo, puedes usar Couchbase Mobile, incluyendo Sync Gateway, en muchos otros escenarios.  Couchbase Lite y Sync Gateway funcionan en una amplia gama de plataformas, y normalmente son f\u00e1ciles de portar a otras nuevas.  Esto hace que Couchbase Mobile sea \u00fatil para cualquier cosa, desde ordenadores de sobremesa (o quiz\u00e1s deber\u00eda decir port\u00e1tiles) hasta IoT.<\/p>\n<p style=\"color: #333333;font-size: 15px\">Estas son algunas de las caracter\u00edsticas clave que hay que conocer sobre las r\u00e9plicas de Sync Gateway en general:<\/p>\n<ul style=\"color: #333333;font-size: 15px\">\n<li style=\"color: inherit;font-style: inherit;font-weight: inherit;line-height: 1.625\">Configuraci\u00f3n JSON para especificar las r\u00e9plicas<\/li>\n<li style=\"color: inherit;font-style: inherit;font-weight: inherit;line-height: 1.625\">Admite varias r\u00e9plicas simult\u00e1neas<\/li>\n<li style=\"color: inherit;font-style: inherit;font-weight: inherit;line-height: 1.625\">Puede realizar r\u00e9plicas tanto en modo \"OneShot\" como en modo \"Continuous\".<\/li>\n<li style=\"color: inherit;font-style: inherit;font-weight: inherit;line-height: 1.625\">No almacena nada de forma persistente<\/li>\n<li style=\"color: inherit;font-style: inherit;font-weight: inherit;line-height: 1.625\">Sin estado: puede interrumpirse o reiniciarse en cualquier momento sin efectos secundarios negativos.<\/li>\n<li style=\"color: inherit;font-style: inherit;font-weight: inherit;line-height: 1.625\">Filtrar las r\u00e9plicas mediante canales<\/li>\n<\/ul>\n<h2 style=\"font-size: 15px\">Replicaci\u00f3n entre instancias<\/h2>\n<p style=\"color: #333333;font-size: 15px\">La versi\u00f3n 1.3 a\u00f1ade una nueva funci\u00f3n a Sync Gateway: la capacidad de replicar (sincronizar) entre instancias de Sync Gateway.  Cada replicaci\u00f3n se configura como un flujo unidireccional entre dos puntos finales.  Esto las hace bastante flexibles.<\/p>\n<p style=\"color: #333333;font-size: 15px\">Por ejemplo, una replicaci\u00f3n sencilla puede especificar dos bases de datos en la misma instancia de Sync Gateway.  Esto puede no parecer tan interesante, pero dado que cada base de datos puede tener su propia funci\u00f3n de sincronizaci\u00f3n, puede utilizar una base de datos como alimentador de otra, permitiendo que una l\u00f3gica empresarial compleja gestione lo que se transmite.<\/p>\n<p style=\"color: #333333;font-size: 15px\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-220\" style=\"color: inherit;font-style: inherit;font-weight: inherit;line-height: 1.625;height: auto;max-width: 97.5%;border: 1px solid #dddddd;padding: 6px;margin-top: 0.4em;width: auto\" src=\"\/wp-content\/original-assets\/2016\/august\/new-couchbase-mobile-v1.3-inter-instance-replication-sync-gateway\/sg-inter-instance.png\" alt=\"running-replications\" width=\"1920\" height=\"776\" \/><\/p>\n<p style=\"color: #333333;font-size: 15px\">Este diagrama muestra un caso de uso m\u00e1s t\u00edpico.  Aqu\u00ed, tenemos dos clusters de Couchbase Server, y dos clusters de Sync Gateway.  Los clusters Sync Gateway ejecutan una replicaci\u00f3n bidireccional (en realidad, dos r\u00e9plicas unidireccionales).  Esto podr\u00eda constituir la base de un sistema distribuido globalmente.  Los procedimientos est\u00e1ndar de enrutamiento de red garantizar\u00edan que los clientes se conectaran al Sync Gateway m\u00e1s cercano, mejorando el rendimiento de la red.  Para m\u00e1s detalles sobre la replicaci\u00f3n en Sync Gateway, eche un vistazo a la documentaci\u00f3n\u00a0<a style=\"color: #1b8be0;font-style: inherit;font-weight: inherit;line-height: 1.625;text-decoration: none\" href=\"https:\/\/developer.couchbase.com\/documentation\/mobile\/current\/develop\/guides\/sync-gateway\/running-replications\/index.html\">aqu\u00ed<\/a>.<\/p>\n<h2 style=\"font-size: 15px\">Revisiones de documentos y conflictos<\/h2>\n<p style=\"color: #333333;font-size: 15px\">Es importante entender c\u00f3mo Couchbase Mobile maneja la resoluci\u00f3n de conflictos.  CBM usa lo que se conoce como control de concurrencia multiversi\u00f3n.  Puedes pensar que CBM no almacena s\u00f3lo una versi\u00f3n de un documento, sino m\u00e1s bien un \u00e1rbol de revisiones.  Dos escrituras desconectadas que actualicen la misma revisi\u00f3n original de un documento crean dos nuevas revisiones.  Ambas existen en el \u00e1rbol.  Couchbase te da varias formas de resolver el conflicto.
