Both Couchbase Server and Couchbase mobile (Sync Gateway and Couchbase Lite) support local transactions. Here we provide details on how Couchbase Server's [Couchbase Transactions](../../../server/current/learn/data/transactions.md) feature relates to the Couchbase mobile ecosystem. ## [](#local-transactions)Local Transactions Within the Couchbase mobile ecosystem all transactions are local, either to the Couchbase Server or to the Couchbase Lite database: * Couchbase Server supports server side transactions — see: [Couchbase Transactions](../../../server/current/learn/data/transactions.md). Changes made on the server within a transaction block are guaranteed to be imported by the Sync Gateway only after all the changes in a transaction are committed. * Similarly, Couchbase Lite supports transactions that are local to the Couchbase Lite database — see: [Database.inBatch()](http://docs.couchbase.com/mobile/4.1.0/couchbase-lite-swift/Classes/Database.html#/s:18CouchbaseLiteSwift8DatabaseC7inBatch5usingyyyKXE%5FtKF). Only committed transactions will ever reach Sync Gateway. There is no guarantee that a series of updates made within a transaction block, on either the Couchbase Server or Couchbase Lite client side, will be ACID compliant when they sync to the other end. --- ##### ## [](#related-content)Related Content ###### [](#-2) Learn more …​ * [Sync Function](../access-control/sync-function/sync-function.md) * [Import filter](../sync/import-processing.md) * [Access Control](../configuration/configuration-schema-access-control.md) * [Add/Update Sync Function](../rest-api/rest%5Fapi%5Fadmin.md#tag/Database-Configuration/operation/put%5Fkeyspace-%5Fconfig-sync) * [Sync Function Overview](../access-control/sync-function/sync-function.md) ###### [](#-3) Reference material …​ * [Public REST API](../rest-api/rest-api.md) * [Admin REST API](../rest-api/rest-api-admin.md) * [Metrics REST API](../rest-api/rest-api-metrics.md) ###### [](#-4) Community [Mobile Forum](https://forums.couchbase.com/c/mobile/14) | [Blog](https://blog.couchbase.com/) | [Blog (Mobile)](https://blog.couchbase.com/category/couchbase-mobile/?ref=blog-menu) | [Tutorials](https://docs.couchbase.com/tutorials/) Sync Function Blogs * [Using roles in sync functions](https://blog.couchbase.com/augment-your-sync-function-with-roles-in-couchbase-sync-gateway/) * [Tutorial: Getting Started with Data Synchronization using Couchbase Mobile for Offline-First Apps](https://blog.couchbase.com/data-synchronization-offline-first-apps-couchbase/) * [Sync Function (category)](https://blog.couchbase.com/tag/sync-function/)
