## Supported Messaging Systems

While each system has its own characteristics and API behavior, the ETLBox connectors abstract the complexity and provide a consistent way to incorporate message-based inputs and outputs into your ETL workflows.


| System             | Type               | Package                        |
|--------------------|--------------------|--------------------------------|
| [Apache Kafka](../kafka)       | Distributed Log    | `ETLBox.Apache.Kafka`            |
| [Azure Service Bus](../service-bus)  | Queue / Pub-Sub    | `ETLBox.Azure.ServiceBus`        |


Refer to the individual connector documentation for usage examples and configuration options.

### Installation

To use a messaging connector, install the corresponding NuGet package. For example, to use the Kafka integration:

{{< tabs "nuget-options" >}}
{{< tab "dotnet CLI" >}}
```cmd
dotnet add package ETLBox.Apache.Kafka
```
{{< /tab >}}
{{< tab "Package Manager" >}}
```ps1
PM> NuGet\Install-Package ETLBox.Apache.Kafka
```
{{< smallnote >}}
This command is intended to be used within the Package Manager Console in Visual Studio, as it uses the NuGet module's version of {{< link-ext url="https://docs.microsoft.com/nuget/reference/ps-reference/ps-ref-install-package" text="Install-Package" >}}.
