Couchbase Server is an open source, distributed, JSON document database. It exposes a scale-out, key-value store with managed cache for sub-millisecond data operations, purpose-built indexers for efficient queries, and a powerful query engine for executing SQL-like queries. For mobile and Internet of Things environments Couchbase also runs natively on-device and manages synchronization to the server. try { final QueryResult result = cluster.query("SELECT * FROM `travel-sample`.inventory.airline LIMIT 100", queryOptions().metrics(true)); for (JsonObject row : result.rowsAsObject()) { System.out.println("Found row: " + row); } System.out.println("Reported execution time: " + result.metaData().metrics().get().executionTime()); } catch (CouchbaseException ex) { ex.printStackTrace(); } ## Get Started ###### New to Couchbase Read the Getting Started guide for step-by-step instructions to create and connect to the database and run your first query. [Get Started](../server/current/getting-started/start-here.md) ###### Upgrading to v8.x If you are an existing Couchbase user looking for information to upgrade to Couchbase Server 8.x and use collections and scopes, see [Upgrade and migrate your data to v8.x](../server/current/install/migrating-application-data.md). ###### Migrating to Couchbase Find guidance and considerations when migrating from a different database to Couchbase through this [blog series](https://blog.couchbase.com/moving-from-sql-server-to-couchbase-part-1-data-modeling/). ###### Explore Tutorials Explore Couchbase [Tutorials](https://developer.couchbase.com/tutorials/) to learn how to build and operate apps using Couchbase. ###### ##
