Azure Event Hubs enables you to automatically capture the streaming data in Event Hubs in an Azure Blob storage or Azure Data Lake Storage Gen 1 or Gen 2 account of your choice, with the added flexibility of specifying a time or size interval : Capture streaming events - Azure Event Hubs

Data Capture with Event Hub

  • The destination storage (Azure Storage or Azure Data Lake Storage) account must be in the same subscription as the event hub.

  • Event Hubs doesn't support capturing events in a premium storage account.

How does Capture work ?

A window (a minimum size and time configuration) is set up to control capturing. Each partition captures independently and writes a completed block blob at the time of capture, named for the time at which the capture interval was encountered.
