Each book explains Real-Time hub in context, with comparison tables and the common traps.
Terms in this definition
- Microsoft Fabric
Analytics platform from Microsoft delivered as SaaS on top of OneLake, offering capabilities including Direct Lake and shortcuts.
- Virtual hub
Inside a Virtual WAN, a VNet managed by Microsoft that contains the hub router plus the VPN, ExpressRoute and User VPN gateways. Typically there is one per region, but several hubs can share a region.
- Streaming data
Events that keep arriving without end, for example log entries, sensor readings or social media posts; stream processing is how they are handled.
- KQL
Kusto Query Language, used read-only to query Azure Data Explorer, Log Analytics and Microsoft Sentinel; log alert rules are written in it too.
- Fabric events
Events raised by Fabric itself and listed in Real-Time hub, for example about workspace items, OneLake, jobs or capacity overview. An eventstream can carry them onward, or Activator can raise alerts from them.
Related terms
- Azure Blob Storage events
Notifications in Real-Time hub, for instance
Microsoft.Storage.BlobCreatedorMicrosoft.Storage.BlobDeleted, that fire when a blob or directory changes in a general-purpose v2 or Blob Storage account. They describe changes rather than carrying business records, and can drive an eventstream or an Activator alert. - Azure events
One of the Real-Time hub's categories, listing system-level events emitted by Azure services (Blob Storage events, say). Each can be streamed into an eventstream, or Activator can raise alerts on it.
- Capacity Overview Events
Real-Time hub events emitted by a Fabric capacity. Twice a minute a Summary event reports smoothed CU use and how much throttling is happening, and a State event fires on pausing, resuming or overload; Activator can alert on them, or an eventhouse can keep them as history.
- Derived stream
Created when an eventstream's default stream is transformed, for instance with Filter or Manage fields. It can feed further destinations and shows up in Real-Time hub where colleagues can reuse it.
- OneLake events
Notifications Fabric emits on file or folder creation, deletion or renaming inside OneLake; Microsoft.Fabric.OneLake.FileCreated is one such type. Real-Time hub can forward them into an eventstream or let them trigger an Activator alert.
- Real-Time Intelligence
Microsoft Fabric's workload for data in motion. Using eventstreams, eventhouses with KQL databases, the Real-Time hub, Real-Time Dashboards and Activator, it takes in events, processes, stores and analyses them, and acts on them.
