SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Managing Fabric Eventstream real-time ingestion pipelines requires navigating complex REST APIs, base64-encoded definitions, LRO polling, and strict topology rules, which is error-prone when done manually.

Core Features & Use Cases

  • Authoring mode: Create Eventstreams, deploy full topologies with sources, operators, and destinations, update definitions, pause/resume, and delete items via the Fabric REST API.
  • Consumption mode: List and inspect Eventstreams, decode topology graphs, check retention and throughput settings, validate configurations, and retrieve Custom Endpoint connection metadata.
  • Use Case: Ask the assistant to create an Eventstream with a SampleData source, add a Filter operator for high-temperature events, and wire the output to a Lakehouse destination, with all API calls, base64 encoding, and LRO polling handled correctly.

Quick Start

Ask the assistant to create an Eventstream named SensorIngestion in your dev workspace with a sample data source and a Lakehouse destination.

Frequently Asked Questions about eventstream-cli

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a Fabric Eventstream with the REST API?▼

Create the item with POST /v1/workspaces/{id}/eventstreams, then build the topology JSON and submit it base64-encoded via POST .../updateDefinition. Alternatively, use POST /items with an inline definition to create the Eventstream and topology in one call.

How do I add a filter operator to an Eventstream?▼

Retrieve the current definition with POST .../getDefinition, decode the base64 eventstream.json, add a Filter node whose column and value use nested objects with expressionType, then re-encode and submit via updateDefinition. Bare string column references are silently rejected.

How do I get the Kafka connection string for an Eventstream Custom Endpoint?▼

Call GET .../eventstreams/{id}/topology to find the Custom Endpoint source ID, then GET .../sources/{sourceId}/connection. This returns the namespace, event hub name, and access keys, and requires the Eventstream.ReadWrite.All scope plus explicit user confirmation.

Why does my Eventstream updateDefinition call return 202 Accepted?▼

The definition APIs are long-running operations that return 202 with a Location header. Poll the Location URL until the status is Succeeded before treating the update as complete.

What are the naming limits for Eventstream topology nodes?▼

User-defined node names must be alphanumeric PascalCase with no hyphens, underscores, dots, or spaces. The platform-generated DefaultStream name is the exception, and a topology may contain at most 11 CustomEndpoint and direct-ingestion nodes.

Can I query event data through the Eventstream API?▼

No. The Eventstream API manages topology and configuration only. To query landed event data, use the eventhouse-cli consumption mode against the Eventhouse or KQL Database where the events are stored.
