To exchange data with other platforms, we offer various Big Data Connectors. ```scala val json = JsonObject("foo" -> "bar", "baz" -> "qux") collection.reactive.upsert("document-key", json) .doOnError(err => println(s"Error during upsert: ${err}")) .doOnNext(_ => println("Success")) .subscribe() ``` > [!TIP] > Analytics SDKs > > SDKs for [Enterprise Analytics](../enterprise-analytics/current/intro/intro.md) — Couchbase's analytical database (RT-OLAP) for real time apps and operational intelligence — are [available](analytics-sdk.md) for the Go, Java, Node.js, and Python platforms. > > SDKs for [Capella Analytics](../analytics/intro/intro.md) are similar to the Enterprise Analytics SDKs. They must be used to connect to the current Capella Analytics Service, as it presents a different connection interface, without Enterprise Analytics' load balancer. They are [available](columnar-sdk.md) for the Go, Java, Node.js, and Python platforms. ## Server SDKs The Couchbase SDKs allow applications to access a Couchbase cluster. They offer traditional synchronous APIs as well as scalable asynchronous APIs to maximize performance. | SDK | Documentation | Hello World Example | API Reference | | ----------- | ----------------------------------------------------- | ------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------- | | .NET SDK | [Docs](../dotnet-sdk/current/hello-world/overview.md) | [.NET Getting Started](../dotnet-sdk/current/hello-world/start-using-sdk.md) | [.NET API Reference](https://docs.couchbase.com/sdk-api/couchbase-net-client) | | C SDK | [Docs](../c-sdk/current/hello-world/overview.md) | [C Getting Started](../c-sdk/current/hello-world/start-using-sdk.md) | [C API Reference](https://docs.couchbase.com/sdk-api/couchbase-c-client/index.html) | | C++ SDK | [Docs](../cxx-sdk/current/hello-world/overview.md) | [C++ Getting Started](../cxx-sdk/current/hello-world/start-using-sdk.md) | [C++ API Reference](https://docs.couchbase.com/sdk-api/couchbase-cxx-client/index.html) | | Go SDK | [Docs](../go-sdk/current/hello-world/overview.md) | [Go Getting Started](../go-sdk/current/hello-world/start-using-sdk.md) | [Go API Reference](https://pkg.go.dev/github.com/couchbase/gocb/v2) | | Java SDK | [Docs](../java-sdk/current/hello-world/overview.md) | [Java Getting Started](../java-sdk/current/hello-world/start-using-sdk.md) | [Java API Reference](https://docs.couchbase.com/sdk-api/couchbase-java-client) | | Kotlin SDK | [Docs](../kotlin-sdk/current/hello-world/overview.md) | [Kotlin Getting Started](../kotlin-sdk/current/hello-world/start-using-sdk.md) | [Kotlin API Reference](https://docs.couchbase.com/sdk-api/couchbase-kotlin-client) | | Node.js SDK | [Docs](../nodejs-sdk/current/hello-world/overview.md) | [Node.js Getting Started](../nodejs-sdk/current/hello-world/start-using-sdk.md) | [Node.js API Reference](https://docs.couchbase.com/sdk-api/couchbase-node-client/modules.html) | | PHP SDK | [Docs](../php-sdk/current/hello-world/overview.md) | [PHP Getting Started](../php-sdk/current/hello-world/start-using-sdk.md) | [PHP API Reference](https://docs.couchbase.com/sdk-api/couchbase-php-client/namespaces/couchbase.html) | | Python SDK | [Docs](../python-sdk/current/hello-world/overview.md) | [Python Getting Started](../python-sdk/current/hello-world/start-using-sdk.md) | [Python API Reference](https://docs.couchbase.com/sdk-api/couchbase-python-client/) | | Ruby SDK | [Docs](../ruby-sdk/current/hello-world/overview.md) | [Ruby Getting Started](../ruby-sdk/current/hello-world/start-using-sdk.md) | [Ruby API Reference](https://docs.couchbase.com/sdk-api/couchbase-ruby-client/Couchbase.html) | | Rust SDK | [Docs](../rust-sdk/current/hello-world/overview.md) | [Rust Getting Started](../rust-sdk/current/hello-world/start-using-sdk.md) | [Rust API Reference](https://docs.rs/couchbase/) | | Scala SDK | [Docs](../scala-sdk/current/hello-world/overview.md) | [Scala Getting Started](../scala-sdk/current/hello-world/start-using-sdk.md) | [Scala API Reference](https://docs.couchbase.com/sdk-api/couchbase-scala-client/com/couchbase/client/scala/index.html) | ###### ###### ### Alternatives to SDKs The Data API gives access to data in Capella Operational clusters — for when to use the Data API, or Capella's other REST APIs, see [Data API vs. Couchbase SDKs](../cloud/data-api-guide/data-api-sdks.md). ###### ###### ## SDK Extension Libraries The SDK Extension Libraries are shipped as separate libraries. ###### Field Level Encryption Fields within a JSON document can be securely encrypted by the SDK to support FIPS 140-2 compliance. This is a client-side implementation, with encryption and decryption handled by the Couchbase client SDK. [Field Level Encryption](../sdk-extensions/field-level-encryption.md) ###### Response Time Observability Health indicators can tell you a lot about the performance of an application. Monitoring them is vital both during its development and production lifecycle. For a database, performance is best encapsulated via per-request performance. [Response Time Observability](../sdk-extensions/response-time-observability.md) ###### Distributed ACID Transactions Previously, distributed ACID transactions were available as separate libraries for some of the SDKs. Please note that this feature, available now in most of the SDKs, is incorporated directly into these SDKs. [Distributed ACID Transactions](../sdk-extensions/distributed-acid-transactions.md) ## Enterprise Analytics SDKs [Enterprise Analytics](../enterprise-analytics/current/intro/intro.md) is an analytical database (RT-OLAP) for real time apps and operational intelligence. [Analytics SDKs](analytics-sdk.md) are tailored to the APIs offered by this service. | Analytics SDK | Documentation | Hello World Example | API Reference | | --------------------- | --------------------------------------------------------------- | ----------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------- | | .NET Analytics SDK | [Docs](../dotnet-analytics-sdk/current/hello-world/overview.md) | [.NET Getting Started](../dotnet-analytics-sdk/current/hello-world/start-using-sdk.md) | [.NET Analytics API Reference](https://docs.couchbase.com/sdk-api/analytics-dotnet-client) | | Go Analytics SDK | [Docs](../go-analytics-sdk/current/hello-world/overview.md) | [Go Getting Started](../go-analytics-sdk/current/hello-world/start-using-sdk.md) | [Go Analytics API Reference](https://pkg.go.dev/github.com/couchbase/gocbanalytics) | | Java Analytics SDK | [Docs](../java-analytics-sdk/current/hello-world/overview.md) | [Java Getting Started](../java-analytics-sdk/current/hello-world/start-using-sdk.md) | [Java Analytics API Reference](https://docs.couchbase.com/sdk-api/couchbase-analytics-java-client) | | Node.js Analytics SDK | [Docs](../nodejs-analytics-sdk/current/hello-world/overview.md) | [Node.js Getting Started](../nodejs-analytics-sdk/current/hello-world/start-using-sdk.md) | [Node.js Analytics API Reference](https://docs.couchbase.com/sdk-api/analytics-nodejs-client/) | | Python Analytics SDK | [Docs](../python-analytics-sdk/current/hello-world/overview.md) | [Python Getting Started](../python-analytics-sdk/current/hello-world/start-using-sdk.md) | [Python Analytics API Reference](https://docs.couchbase.com/sdk-api/analytics-python-client/) | ## Capella Analytics SDKs [Capella Analytics](../analytics/intro/intro.md) is an analytical database (RT-OLAP) for real time apps and operational intelligence.
