    An Event Hubs namespace provides a unique scoping container, referenced by its fully qualified domain name, in which you create one or more event hubs or Kafka topics.

    This feature provides an endpoint that enables customers to talk to Event Hubs using the Kafka protocol. This integration provides customers a Kafka endpoint. This enables customers to configure their existing Kafka applications to talk to Event Hubs, giving an alternative to running their own Kafka clusters. Event Hubs for Apache Kafka supports Kafka protocol 1.0 and later.With this integration, you don't need to run Kafka clusters or manage them with Zookeeper. This also allows you to work...

    Any entity that sends data to an event hub is an event producer, or event publisher. Event publishers can publish events using HTTPS or AMQP 1.0 or Kafka 1.0 and later. Event publishers use a Shared Access Signature (SAS) token to identify themselves to an event hub, and can have a unique identity, or use a common SAS token.

    Event Hubs Capture enables you to automatically capture the streaming data in Event Hubs and save it to your choice of either a Blob storage account, or an Azure Data Lake Service account. You can enable Capture from the Azure portal, and specify a minimum size and time window to perform the capture. Using Event Hubs Capture, you specify your own Azure Blob Storage account and container, or Azure Data Lake Service account, one of which is used to store the captured data. Captured data is writ...

    Event Hubs provides message streaming through a partitioned consumer pattern in which each consumer only reads a specific subset, or partition, of the message stream. This pattern enables horizontal scale for event processing and provides other stream-focused features that are unavailable in queues and topics.A partition is an ordered sequence of events that is held in an event hub. As newer events arrive, they are added to the end of this sequence. A partition can be thought of as a \\"commit...

    Event Hubs uses Shared Access Signatures, which are available at the namespace and event hub level. A SAS token is generated from a SAS key and is an SHA hash of a URL, encoded in a specific format. Using the name of the key (policy) and the token, Event Hubs can regenerate the hash and thus authenticate the sender. Normally, SAS tokens for event publishers are created with only send privileges on a specific event hub. This SAS token URL mechanism is the basis for publisher identification int...

    Any entity that reads event data from an event hub is an event consumer. All Event Hubs consumers connect via the AMQP 1.0 session and events are delivered through the session as they become available. The client does not need to poll for data availability.

    Data is valuable only when there is an easy way to process and get timely insights from data sources. Event Hubs provides a distributed stream processing platform with low latency and seamless integration, with data and analytics services inside and outside Azure to build your complete big data pipeline.Event Hubs represents the \\"front door\\" for an event pipeline, often called an event ingestor in solution architectures. An event ingestor is a component or service that sits between event publ...

    Event Hubs is a fully managed Platform-as-a-Service (PaaS) with little configuration or management overhead, so you focus on your business solutions. Event Hubs for Apache Kafka ecosystems gives you the PaaS Kafka experience without having to manage, configure, or run your clusters.

    Ingest, buffer, store, and process your stream in real time to get actionable insights. Event Hubs uses a partitioned consumer model, enabling multiple applications to process the stream concurrently and letting you control the speed of processing.Capture your data in near-real time in an Azure Blob storage or Azure Data Lake Storage for long-term retention or micro-batch processing. You can achieve this behavior on the same stream you use for deriving real-time analytics. Setting up capture...

    With Event Hubs, you can start with data streams in megabytes, and grow to gigabytes or terabytes. The Auto-inflate feature is one of the many options available to scale the number of throughput units to meet your usage needs.

    Event Hubs for Apache Kafka ecosystems enables Apache Kafka (1.0 and later) clients and applications to talk to Event Hubs. You do not need to set up, configure, and manage your own Kafka clusters.With a broad ecosystem available in various languages (.NET, Java, Python, Go, Node.js), you can easily start processing your streams from Event Hubs. All supported client languages provide low-level integration. The ecosystem also provides you with seamless integration with Azure services like Azur...

    Event Hubs contains the following key components: 1. Event producers: Any entity that sends data to an event hub. Event publishers can publish events using HTTPS or AMQP 1.0 or Apache Kafka (1.0 and above) 2. Partitions: Each consumer only reads a specific subset, or partition, of the message stream. 3. Consumer groups: A view (state, position, or offset) of an entire event hub. Consumer groups enable consuming applications to each have a separate view of the event stream. They read the strea...

    The template used in this quickstart is from Azure Quickstart templates. The resources defined in the template include: 1. Microsoft.EventHub/namespaces 2. Microsoft.EventHub/namespaces/eventhubs To find more template samples, see Azure Quickstart Templates.

    Deploy the template

    To deploy the template: 1. Select Try it from the following code block, and then follow the instructions to sign in to the Azure Cloud Shell.Azure PowerShell $projectName = Read-Host-Prompt "Enter a project name that is used for generating resource names"$location = Read-Host-Prompt "Enter the location (i.e. centralus)"$resourceGroupName = "${projectName}rg"$templateUri = "https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/101-eventhubs-create-namespace-and-eventhub/azu...

    To verify the deployment, you can either open the resource group from the Azure portal, or use the following Azure PowerShell script. If the Cloud Shell is still open, you don't need to copy/run the first line (Read-Host).

    When the Azure resources are no longer needed, clean up the resources you deployed by deleting the resource group. If the Cloud Shell is still open, you don't need to copy/run the first line (Read-Host).
