Fabric-to-Fabric Data Sharing

Fabric-to-Fabric data sharing enables seamless sharing of datasets between Nexalis and your Microsoft Fabric workspace through OneLake shortcuts and External Data Shares.

​
OneLake Shortcuts

OneLake shortcuts allow you to access data stored in Nexalis’ Fabric lakehouse directly within your own Fabric workspace without copying or moving the data. This provides:
  • Zero data duplication — Access shared data in-place
  • Real-time access — Always see the latest data from Nexalis
  • No egress costs — Nexalis stores data in your desired Azure region
  • Native Fabric integration — Works with all Fabric compute engines (Spark, SQL, Power BI, etc.)

​
How It Works

Nexalis uses Microsoft Fabric’s External Data Share feature to create OneLake shortcuts in your workspace. These shortcuts point directly to Delta tables in Nexalis’ lakehouse, providing real-time access without data duplication.

​
Required Information

To configure Fabric-to-Fabric sharing, Nexalis needs an email address in your Microsoft organization and your Azure Tenant ID. How to find it:
  • In Fabric: Click on your profile icon in the top right corner → click the small info circle next to your tenant name → copy your tenant ID.
  • In Azure Portal: Navigate to Microsoft Entra ID → copy your tenant ID.

​
2. Enable Data Sharing in Fabric

Your Fabric organization must have the “Users can accept external data shares” setting enabled. How to enable:
  1. Go to Fabric Admin Portal (gear icon → Admin portal)
  2. Navigate to Tenant settings
  3. Under External data sharing, find “Users can accept external data shares”
  4. Toggle the setting to Enabled
  5. Click Apply
⚠️ Note: This setting must be enabled by a Fabric administrator before you can receive data shares from Nexalis.

​
Setup Process

  1. Collect the required information listed above
  2. Share credentials securely with your Nexalis account manager or support contact
  3. Nexalis configures the OneLake shortcuts in your specified lakehouse
  4. Verify access to shared tables in your Fabric workspace
⚠️ Recommendation: To minimize latency and avoid egress costs, use a Fabric workspace in the same Azure region as the Nexalis environment.

​
After Setup

Once configured, you will see shortcuts to Nexalis shared tables directly in your Fabric lakehouse under the Files directory:
  • gold_<org_name>_avg_std/ — Aggregated time-series data with averages and standard deviations
  • gold_<org_name>_hf_std/ — High-frequency time-series data in standardized format
These shortcuts behave like native Delta tables and can be queried using:
  • SQL endpoints in Fabric
  • Power BI for visualization
  • Spark notebooks for data processing
  • Data pipelines for orchestration

​
Example: Querying Shared Data

-- Query aggregated data in SQL endpoint
SELECT 
    siteName,
    deviceID,
    dataPoint,
    timestamp,
    avg_value,
    std_value
FROM gold_yourcompany_avg_std
WHERE siteName = 'site_A'
    AND timestamp >= '2025-01-01'
ORDER BY timestamp DESC
LIMIT 100;

​
Security

  • Access control is managed through Azure RBAC and Fabric workspace permissions
  • Service principal should follow least-privilege principles
  • Credentials are stored securely by Nexalis and rotated periodically
  • Audit logs track all data access through Fabric’s built-in monitoring

​
After setup

After Nexalis completes the configuration, you will see the shared tables directly in your Fabric workspace:
  • gold_<org_name>_avg_std
  • gold_<org_name>_hf_std
