Technical Guide

Implementation Guide

Step-by-step configuration for production-ready deployment.

Multi-Broker Cluster Setup

Configure high-availability Kafka cluster with proper replication and security settings.

1
Broker Configuration

Set replication.factor=3, min.insync.replicas=2

2
Topic Partitioning

Configure 6+ partitions for parallel processing

3
Security Protocol

Enable SASL_SSL with SCRAM-SHA-512

server.properties
# Multi-Broker Configuration
broker.id=1
listeners=SASL_SSL://broker1:9093
security.inter.broker.protocol=SASL_SSL
sasl.mechanism.inter.broker.protocol=SCRAM-SHA-512

# Replication Settings
default.replication.factor=3
min.insync.replicas=2
unclean.leader.election.enable=false

# Performance Tuning
num.network.threads=8
num.io.threads=16
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400

# ACLs & Security
authorizer.class.name=kafka.security.authorizer.AclAuthorizer
allow.everyone.if.no.acl.found=false
super.users=User:admin

Microsoft Fabric Configuration

Set up Eventstream and Lakehouse destination for Kafka ingestion.

Eventstream Creation

Create new Eventstream with Kafka connector enabled

Lakehouse Destination

Configure bronze layer table with schema auto-detection

fabric-config.json
{
  "eventstream": {
    "name": "kafka-events-stream",
    "source": {
      "type": "kafka",
      "bootstrapServers": "broker1:9093,broker2:9093",
      "topic": "user-events",
      "consumerGroup": "fabric-consumer-v1",
      "security": {
        "protocol": "SASL_SSL",
        "mechanism": "SCRAM-SHA-512",
        "username": "fabric-user",
        "passwordRef": "keyvault-secret-uri"
      }
    },
    "destination": {
      "lakehouse": {
        "workspace": "analytics-prod",
        "lakehouse": "streaming-lakehouse",
        "table": "bronze_events",
        "format": "delta",
        "mergeSchema": true
      }
    }
  }
}

Eventstream Kafka Connector

Real-time ingestion configuration with error handling and retries.

Important

Ensure Kafka brokers are accessible from Fabric’s IP ranges or use Private Link.

connector.properties

connector.class=com.microsoft.fabric.kafka.FabricSinkConnector
tasks.max=6

# Kafka Connection
topics=user-events,transactions,logs
key.converter=org.apache.kafka.connect.json.JsonConverter
value.converter=org.apache.kafka.connect.json.JsonConverter

# Fabric Connection

Best Practices

Proven patterns for production success.

1

Idempotent Producers

Enable idempotence in Kafka producers to ensure exactly-once semantics during network failures or broker restarts.

2

Schema Evolution

Use Confluent Schema Registry with backward/forward compatibility modes to handle changing data structures.

3

Dead Letter Queues

Implement DLQs for poison messages to prevent pipeline stalls while maintaining audit trails.

4

Backpressure Handling

Configure buffer sizes and max.poll.records to handle throughput spikes without memory issues.

5

Data Quality Gates

Implement Great Expectations or similar frameworks to validate data before landing in Fabric.

6

Disaster Recovery

Maintain cross-region replication and test failover procedures regularly with automated runbooks.
