Overview

Install-Module Az

Step 1: To begin, log into Fabric

$tenantId = "1234-11111-2222-123141"
Connect-AzAccount -TenantId $tenantId | Out-Null

Step 2: Get the token to authenticate to Fabric

$baseFabricUrl = "https://api.fabric.microsoft.com"
# Get authentication token
    $fabricToken = (Get-AzAccessToken -ResourceUrl $baseFabricUrl).Token
# Setup headers for API call
    $headerParams = @{'Authorization'="Bearer {0}" -f $fabricToken}
    $contentType = @{'Content-Type' = "application/json"}

Step 3: Create Eventhouse

$eventhouseName = "EH_PSTest11"

# Create body of request
$body = @{
'displayName' = $eventhouseName
} | ConvertTo-Json -Depth 1

# Create Eventhouse API
$eventhouseAPI = "https://api.fabric.microsoft.com/v1/workspaces/$workspaceId/eventhouses" 

# Call Eventhouse create API
$eventhouseCreate = Invoke-RestMethod -Headers $headerParams -Method POST -Uri $eventhouseAPI -Body ($body) -ContentType "application/json"
$eventhouseId= ($eventhouseCreate.id).ToString()

Step 4: Create KQL Database in above Eventhouse

$kqlDBName = "KQLDB_PSTest11"

# Create body of request
$body = @{       
            'displayName' = $kqlDBName;
            'creationPayload'= @{
            'databaseType' = "ReadWrite";
            'parentEventhouseItemId' = $eventhouseId}
             } | ConvertTo-Json -Depth 2

# Create KQLDB API
$kqlDBAPI = "https://api.fabric.microsoft.com/v1/workspaces/$workspaceId/kqlDatabases"

# Call KQL DB create API
Invoke-RestMethod -Headers $headerParams -Method GET -Uri $kqlDBAPI -ContentType "application/json" -verbose

Step 5: Create Database entities using a script file

The following code extracts script for a .csl or .kql or .txt file kept locally in the same folder of this PowerShell script and runs the creation of all database entities like Tables, Functions and Materialized Views

# Function to get current directory
function Get-ScriptDirectory {
if ($psise) {
			Split-Path $psise.CurrentFile.FullPath
			}
else {
		$PSScriptRoot
		}
}

# Read script file contents
$DBScriptPath=Get-ScriptDirectory
$DBScriptloc = (Join-Path $DBScriptPath $dbScriptName)
$DBScript=Get-content -Path $DBScriptloc

Authenticating to KQL DB data plane to avoid 401 unauthorized error

# Create Kusto Url to authenticate
$kustoUrl = "https://api.kusto.windows.net"
$kustoToken = (Get-AzAccessToken -ResourceUrl $kustoUrl).Token
$headerParams = @{'Authorization'="Bearer {0}" -f $kustoToken}

# Create Kusto API
$queryAPI = "$queryUri/v1/rest/mgmt"
$DBScript=$DBScript | Out-String

# Create body of the request
$body = @{
'csl' = $DBScript;
'db'= $kqlDBName
} | ConvertTo-Json -Depth 1

# Call Kusto API to run entities creation script
Invoke-RestMethod -Headers $headerParams -Method POST -Uri $queryAPI -Body ($body) -ContentType "application/json; charset=utf-8"

Step 6: Eventhouse and all its entities are created!

Conclusion

By constructing a simple PowerShell script, we are able to automate creation of Fabric Real-Time Intelligence Eventhouse items. We can modify the PowerShell script to take parameters as inputs, handle errors using try/catch blocks and wrap it up to run as single command. You can visit SuryaTejJosyula/FabricRTI_Accelerator (github.com) to get a full PowerShell script and instructions of running it.
