    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...

    • Throughput Units
    • Partitions
    • Next Steps

    The throughput capacity of Event Hubs is controlled by throughput units. Throughput units are pre-purchased units of capacity. A single throughput lets you: 1. Ingress: Up to 1 MB per second or 1000 events per second (whichever comes first). 2. Egress: Up to 2 MB per second or 4096 events per second. Beyond the capacity of the purchased throughput units, ingress is throttled and a ServerBusyException is returned. Egress does not produce throttling exceptions, but is still limited to the capacity of the purchased throughput units. If you receive publishing rate exceptions or are expecting to see higher egress, be sure to check how many throughput units you have purchased for the namespace. You can manage throughput units on the Scale blade of the namespaces in the Azure portal. You can also manage throughput units programmatically using the Event Hubs APIs. Throughput units are pre-purchased and are billed per hour. Once purchased, throughput units are billed for a minimum of one hou...

    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 log." Event Hubs retains data for a configured retention time that applies across all partitions in the event hub. Events expire on a time basis; you cannot explicitly delete them. Because partitions are independent and contain their own sequence of data, they often grow at different rates. The number of partitions is specified at creation and must be between 2 and 32. The partition count is not changeable, so you should consider long-term scale when setting partition count. Partitions are a da...

    It's important to note the distinction between "outages" and "disasters." An outageis the temporary unavailability of Azure Event Hubs, and can affect some components of the service, such as a messaging store, or even the entire datacenter. However, after the problem is fixed, Event Hubs becomes available again. Typically, an outage does not cause the loss of messages or other data. An example of such an outage might be a power failure in the datacenter. Some outages are only short connection losses due to transient or network issues. A disasteris defined as the permanent, or longer-term loss of an Event Hubs cluster, Azure region, or datacenter. The region or datacenter may or may not become available again, or may be down for hours or days. Examples of such disasters are fire, flooding, or earthquake. A disaster that becomes permanent might cause the loss of some messages, events, or other data. However, in most cases there should be no data loss and messages can be recovered once...

    The disaster recovery feature implements metadata disaster recovery, and relies on primary and secondary disaster recovery namespaces. The Geo-disaster recovery feature is available for the standard and dedicated SKUsonly. You do not need to make any connection string changes, as the connection is made via an alias. The following terms are used in this article: 1. Alias: The name for a disaster recovery configuration that you set up. The alias provides a single stable Fully Qualified Domain Name (FQDN) connection string. Applications use this alias connection string to connect to a namespace. 2. Primary/secondary namespace: The namespaces that correspond to the alias. The primary namespace is "active" and receives messages (this can be an existing or new namespace). The secondary namespace is "passive" and does not receive messages. The metadata between both is in sync, so both can seamlessly accept messages without any application code or connection string changes. To ensure that o...

    The following section is an overview of the failover process, and explains how to set up the initial failover.

    If you made a mistake; for example, you paired the wrong regions during the initial setup, you can break the pairing of the two namespaces at any time. If you want to use the paired namespaces as regular namespaces, delete the alias.

    The sample on GitHubshows how to set up and initiate a failover. This sample demonstrates the following concepts: 1. Settings required in Azure Active Directory to use Azure Resource Manager with Event Hubs. 2. Steps required to execute the sample code. 3. Send and receive from the current primary namespace.

    Note the following considerations to keep in mind with this release: 1. By design, Event Hubs geo-disaster recovery does not replicate data, and therefore you cannot reuse the old offset value of your primary event hub on your secondary event hub. We recommend restarting your event receiver with one of the following: 1. EventPosition.FromStart()- If you wish read all data on your secondary event hub. 2. EventPosition.FromEnd()- If you wish to read all new data from the time of connection to your secondary event hub. 3. EventPosition.FromEnqueuedTime(dateTime)- If you wish to read all data received in your secondary event hub starting from a given date and time. 1. In your failover planning, you should also consider the time factor. For example, if you lose connectivity for longer than 15 to 20 minutes, you might decide to initiate the failover. 2. The fact that no data is replicated means that currently active sessions are not replicated. Additionally, duplicate detection and schedu...

    The Event Hubs Standard SKU supports Availability Zones, providing fault-isolated locations within an Azure region. You can enable Availability Zones on new namespaces only, using the Azure portal. Event Hubs does not support migration of existing namespaces. You cannot disable zone redundancy after enabling it on your namespace.

    The sample on GitHubwalks through a simple workflow that creates a geo-pairing and initiates a failover for a disaster recovery scenario.
    The REST API referencedescribes APIs for performing the Geo-disaster recovery configuration.
