Event Hubs

Azure Event Hubs is a hyper-scale data ingestion service, fully-managed by Microsoft, that enables you to collect, store and process trillions of events from websites, apps, IoT devices, and any stream of data.

How can we improve Azure Event Hubs?

  2. Allow more than 10 hubs per event hub namespace

    Event hub namespaces have a hard limit of 10 hubs. It would be great to be able to raise that limit to 100 or 1000 or whatever via a support request.

    We use Azure Event Hubs with Kafka. A namespace for us is a kafka server and a hub is a kafka topic. Now we have to split topics per kafka server based on Azure's 10 hubs hard limit, which is counterintuitive and complicates our setup.

  3. Diagnostics Logging should also log successful/unsuccessful authentication/authorization requests

    Same as in Azure Search, Cosmos DB and other components, diagnostics logging should also log 401/403 errors when e.g. trying to access Event Hubs with a wrong Token/Key.

    This is important for security reasons to setup e.g. Alerting in Log Analytics to monitor "unsuccessfull authentication/authorization" attempts

  4. Data Lake Gen2 Capture Support

    Currently you can capture to Data Lake Gen1 or Blob but not Data Lake Gen 2. Sad times.

  5. Please add VNET & SE configuration

    We have VNETs configured with express route for on-prem connectivity. Can we have VNETs and SE configuration to connect EVentHub securely from VNET to EventHubs.

  6. please add a group of ip at one time in IP filter

    We try to add 30+ IPs of specified region in azure https://www.microsoft.com/en-sg/download/details.aspx?id=41653. But we find that we have to add it one by one. It is brute force.

    Please help adding a function to add a group of ip/range. We can separate different ip/range with ; or ,

  7. event hubs firewall

    Provide an option to allow azure services access through the firewall for Azure Event Hubs.

    It is common practice to utilize services such as Azure Stream Analytics to consume data from Event Hubs. When enabling the firewall for the event hub service this blocks ASA from connecting. Other services such as ADLS and Azure SQL Database already have this simple option to toggle for their firewall settings. It would be great to have this common option for firewall options across all services.

  8. Show Event Hub usage and quota in Usage + Quotas.

    Please consider showing the Event Hub usage and quota in Usage + Quotas just like it is shown for Storage Accounts.

  9. Please increase the number of event hubs per namespace

    Please increase the number of event hubs per namespace. 10 hubs are not enough.
    Please increase the current limit from 10 to 100 on standard tier.

  10. Emit EventGrid messages when the EventHub is scaled up/down

    Downstream services that consume EventHubs sometimes need to know when an EventHub is scaled up or down so they can react and scale accordingly. It would be really useful if an EventHub emitted this into EventGrid so that downstream services can listen for it and react to it.

  11. Injecting Dynamic Parameters in Event Hubs Capture File Path

    Currently Event Hubs Capture automatically stores events into Data Lake based on predefined paths with placeholders. It would be great if additional parameters could be injected in the path based on event properties dynamically.

    Example: {Namespace}/{EventHub}/{TenantId}/{PartitionId}/{Year}/{Month}/{Day}/{Hour}/{Minute}/{Second}

    TenantId is a property found in every event denoting the originating tenant of the event. This ensures that the Data Lake directory structure can reflect dynamic business requirements.

  12. I want to see number of outgoing messages by consumer group

    I can load up graphs showing outgoing messages by the event hub, but I want to see more granularly down to outgoing messages by the consumer group.

  13. Add more fine-grained ACLs for message listeners

    Currently, a listener of an EventHub has access to all the messages within that EventHub. In the case of untrusted consumers (e.g. in a multi-tenant system), it's sometimes useful to restrict this permission to only read some of the messages in the EventHub.

    A sample scenario is for using a shared Event Hub as a multi-tenant distributed log for a service. As it stands, each customer can already have their own publisher key to the shared Event Hub. It would also be nice if each customer can get a SAS key that only allows them to listen to messages from…

  14. Add information about update on the backend server of namespace

    We received lot of error in
    Metric Namespace : Event Hub standard metrics
    Metric : User Errors. (Preview)

    The support Microsoft Azure told me :

    There is an ongoing update on the backend server for your namespace, during these updates it is expected that you are going to see User Error and Server Errors on a few requests.
    For all these errors the detailed error message should surface into your application code, if you are not seeing any exception on your application probably your client application SDK is retrying the operation successfully so no error is thrown.
    These service/OS updates…
