Ben Johnson, autor del almacenamiento NoSQL BoltDB, present\u00f3 el proyecto Litestream, que proporciona una capa para organizar la replicaci\u00f3n de datos en SQLite. Litestream no requiere modificaciones en SQLite y puede funcionar con cualquier aplicaci\u00f3n que utilice esta biblioteca. La replicaci\u00f3n es gestionada por un proceso en segundo plano que supervisa los cambios en los archivos de la base de datos y los transfiere a otro archivo o almacenamiento externo. El c\u00f3digo del proyecto est\u00e1 escrito en Go y se distribuye bajo la licencia Apache 2.0. <\/p>\n
Toda la interacci\u00f3n con la base de datos se realiza a trav\u00e9s de la API est\u00e1ndar de SQLite, es decir, Litestream no interfiere directamente en su funcionamiento, no afecta el rendimiento y no puede da\u00f1ar el contenido de la base de datos, lo que distingue a Litestream de soluciones como Rqlite y Dqlite. Los cambios se rastrean a trav\u00e9s de la activaci\u00f3n del registro WAL (\"Write-Ahead Log\") en SQLite. Para ahorrar espacio en el almacenamiento, el sistema agrega peri\u00f3dicamente el flujo de cambios en instant\u00e1neas de la base de datos, sobre las cuales comienzan a acumularse otros cambios. El tiempo de creaci\u00f3n de las instant\u00e1neas se puede especificar en la configuraci\u00f3n; por ejemplo, se pueden formar instant\u00e1neas una vez al d\u00eda o cada hora. <\/p>\n
Las principales \u00e1reas de aplicaci\u00f3n de Litestream incluyen la organizaci\u00f3n de copias de seguridad seguras y la distribuci\u00f3n de la carga de lectura en varios servidores<\/a>. Se admite la transferencia del flujo de cambios a los almacenes Amazon S3, Azure Blob Storage, Backblaze B2, DigitalOcean Spaces, Scaleway Object Storage, Google Cloud Storage, Linode Object Storage o cualquier host externo que soporte el protocolo SFTP. En caso de que el contenido de la base de datos principal se da\u00f1e, se puede restaurar una copia de seguridad desde el estado correspondiente a un momento espec\u00edfico, a un cambio particular, al \u00faltimo cambio o a una instant\u00e1nea designada. \u0411\u0435\u043d \u0414\u0436\u043e\u043d\u0441\u043e\u043d (Ben Johnson), \u0430\u0432\u0442\u043e\u0440 NoSQL-\u0445\u0440\u0430\u043d\u0438\u043b\u0438\u0449\u0430 BoltDB, \u043f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u0438\u043b \u043f\u0440\u043e\u0435\u043a\u0442 Litestream, \u043f\u0440\u0435\u0434\u043e\u0441\u0442\u0430\u0432\u043b\u044f\u044e\u0449\u0438\u0439 \u043d\u0430\u0434\u0441\u0442\u0440\u043e\u0439\u043a\u0443 \u0434\u043b\u044f \u043e\u0440\u0433\u0430\u043d\u0438\u0437\u0430\u0446\u0438\u0438 \u0440\u0435\u043f\u043b\u0438\u043a\u0430\u0446\u0438\u0438 \u0434\u0430\u043d\u043d\u044b\u0445 \u0432 SQLite.
