Connect to eventhub using Managed service identity (MSI) from Azure synapse analytics

You need to add the Azure Event Hubs SDK and the Azure Identity SDK for Scala.

Then use the EventHubsConf class to configure the connection to your Event Hub using MSI.

Use the spark.writeStream method to write data to the Event Hub.

// Import necessary libraries

import com.microsoft.azure.eventhubs._

import com.azure.identity._

import org.apache.spark.eventhubs._

import org.apache.spark.sql.functions._

import org.apache.spark.sql.types._

// Define Event Hub connection parameters

val eventHubsNamespace = "<Your Event Hubs Namespace>"

val eventHubName = "<Your Event Hub Name>"

// Define the Managed Identity client

val managedIdentityClientId = "<Your Managed Identity Client ID>" // Optional, if you want to specify a specific managed identity

// Create a token credential using Managed Identity

val credential = new DefaultAzureCredentialBuilder().build()

// Build the EventHubsConf using Managed Identity

val connectionString = new ConnectionStringBuilder(s"Endpoint=sb://${eventHubsNamespace}.servicebus.windows.net/;EntityPath=${eventHubName}")

val eventHubsConf = EventHubsConf(connectionString.toString)

  .setTokenProvider(

    EventHubsUtils.buildTokenProvider(

      connectionString.getEndpoint.toString,

      connectionString.getEntityPath,

      credential

    )

  )

// Sample data to write to Event Hubs

val data = Seq(("Hello, Event Hubs!"))

val df = data.toDF("message")

// Write the data to Event Hubs

val query = df

  .selectExpr("CAST(message AS STRING) AS body")

  .writeStream

  .format("eventhubs")

  .options(eventHubsConf.toMap)

  .option("checkpointLocation", "/mnt/checkpoints")

  .start()

query.awaitTermination()

Is there a way to generate MSI token in Synapse without using mssparkutils for services like ServiceBus and EventHub
