    What is an Event Hubs namespace?

    A namespace is a scoping container for Event Hub/Kafka Topics. It gives you a unique FQDN. A namespace serves as an application container that can house multiple Event Hub/Kafka Topics.

    When do I create a new namespace vs. use an existing namespace?

    Capacity allocations (throughput units (TUs)) are billed at the namespace level. A namespace is also associated with a region. You may want to create a new namespace instead of using an existing one in one of the following scenarios: 1. You need an Event Hub associated with a new region. 2. You need an Event Hub associated with a different subscription. 3. You need an Event Hub with a distinct capacity allocation (that is, the capacity need for the namespace with the added event hub would exc...

    What is the difference between Event Hubs Basic and Standard tiers?

    The Standard tier of Azure Event Hubs provides features beyond what is available in the Basic tier. The following features are included with Standard: 1. Longer event retention 2. Additional brokered connections, with an overage charge for more than the number included 3. More than a single consumer group 4. Capture 5. Kafka integration For more information about pricing tiers, including Event Hubs Dedicated, see the Event Hubs pricing details.

    How do I integrate my existing Kafka application with Event Hubs?

    Event Hubs provides a Kafka endpoint that can be used by your existing Apache Kafka based applications. A configuration change is all that is required to have the PaaS Kafka experience. It provides an alternative to running your own Kafka cluster. Event Hubs supports Apache Kafka 1.0 and newer client versions and works with your existing Kafka applications, tools, and frameworks. For more information, see Event Hubs for Kafka repo.

    What configuration changes need to be done for my existing application to talk to Event Hubs?

    To connect to an event hub, you'll need to update the Kafka client configs. It's done by creating an Event Hubs namespace and obtaining the connection string. Change the bootstrap.servers to point the Event Hubs FQDN and the port to 9093. Update the sasl.jaas.config to direct the Kafka client to your Event Hubs endpoint (which is the connection string you've obtained), with correct authentication as shown below: bootstrap.servers={YOUR.EVENTHUBS.FQDN}:9093request.timeout.ms=60000security.prot...

    What is the message/event size for Event Hubs?

    The maximum message size allowed for Event Hubs is 1 MB.

    What are Event Hubs throughput units?

    Throughput in Event Hubs defines the amount of data in mega bytes or the number (in thousands) of 1-KB events that ingress and egress through Event Hubs. This throughput is measured in throughput units (TUs). Purchase TUs before you can start using the Event Hubs service. You can explicitly select Event Hubs TUs either by using portal or Event Hubs Resource Manager templates.

    Do throughput units apply to all event hubs in a namespace?

    Yes, throughput units (TUs) apply to all event hubs in an Event Hubs namespace. It means that you purchase TUs at the namespace level and are shared among the event hubs under that namespace. Each TU entitles the namespace to the following capabilities: 1. Up to 1 MB per second of ingress events (events sent into an event hub), but no more than 1000 ingress events, management operations, or control API calls per second. 2. Up to 2 MB per second of egress events (events consumed from an event...

    How are throughput units billed?

    Throughput units (TUs) are billed on an hourly basis. The billing is based on the maximum number of units that was selected during the given hour.

    What are Event Hubs Dedicated clusters?

    Event Hubs Dedicated clusters offer single-tenant deployments for customers with most demanding requirements. This offering builds a capacity-based cluster that is not bound by throughput units. It means that you could use the cluster to ingest and stream your data as dictated by the CPU and memory usage of the cluster. For more information, see Event Hubs Dedicated clusters.

    How much does a single capacity unit let me achieve?

    For a dedicated cluster, how much you can ingest and stream depends on various factors such as your producers, consumers, the rate at which you're ingesting and processing, and much more. Following table shows the benchmark results that we achieved during our testing: In the testing, the following criteria was used: 1. A dedicated Event Hubs cluster with four capacity units (CUs) was used. 2. The event hub used for ingestion had 200 partitions. 3. The data that was ingested was received by tw...

    How do I create an Event Hubs Dedicated cluster?

    You create an Event Hubs dedicated cluster by submitting a quota increase support request or by contacting the Event Hubs team. It typically takes about two weeks to get the cluster deployed and handed over to be used by you. This process is temporary until a complete self-serve is made available through the Azure portal.

    How many partitions do I need?

    The number of partitions is specified at creation and must be between 2 and 32. The partition count isn't changeable, so you should consider long-term scale when setting partition count. Partitions are a data organization mechanism that relates to the downstream parallelism required in consuming applications. The number of partitions in an event hub directly relates to the number of concurrent readers you expect to have. For more information on partitions, see Partitions. You may want to set...

    Where can I find more pricing information?

    For complete information about Event Hubs pricing, see the Event Hubs pricing details.

    Is there a charge for retaining Event Hubs events for more than 24 hours?

    The Event Hubs Standard tier does allow message retention periods longer than 24 hours, for a maximum of seven days. If the size of the total number of stored events exceeds the storage allowance for the number of selected throughput units (84 GB per throughput unit), the size that exceeds the allowance is charged at the published Azure Blob storage rate. The storage allowance in each throughput unit covers all storage costs for retention periods of 24 hours (the default) even if the throughp...

    How is the Event Hubs storage size calculated and charged?

    The total size of all stored events, including any internal overhead for event headers or on disk storage structures in all event hubs, is measured throughout the day. At the end of the day, the peak storage size is calculated. The daily storage allowance is calculated based on the minimum number of throughput units that were selected during the day (each throughput unit provides an allowance of 84 GB). If the total size exceeds the calculated daily storage allowance, the excess storage is bi...

    Are there any quotas associated with Event Hubs?

    For a list of all Event Hubs quotas, see quotas.

    Why am I not able to create a namespace after deleting it from another subscription?

    When you delete a namespace from a subscription, wait for 4 hours before recreating it with the same name in another subscription. Otherwise, you may receive the following error message: Namespace already exists.

    What are some of the exceptions generated by Event Hubs and their suggested actions?

    For a list of possible Event Hubs exceptions, see Exceptions overview.

    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.
