Serialization Formats

This integration supports all four major serialization formats used in modern data engineering:

Format	Schema Support	Validation	Registry	Performance	Best For
JSON	❌	❌	❌	Good	Simple events, logs
JSON Schema	✅	✅	❌	Good	Data quality enforcement
Avro	✅	✅	✅	Better	Schema evolution, analytics
Protobuf	✅	✅	✅	Best	High-performance, microservices

JSON Schema Validation

Enforce data quality with automatic validation

Features

• Automatic Validation: Messages validated against JSON Schema on consumption
• Flexible Modes: Strict (fail on invalid) or lenient (warn and continue)
• Schema Evolution: Track schema changes and compatibility
• DLQ Integration: Invalid messages automatically routed for investigation
• File or Inline: Load schemas from files or define inline

Basic Usage

from dagster_kafka import create_json_schema_kafka_io_manager

# Using schema file
json_schema_manager = create_json_schema_kafka_io_manager(
    kafka_resource=kafka_resource,
    schema_file="schemas/user_events.json",
    enable_schema_validation=True,
    strict_validation=True
)

# Using inline schema
json_schema_manager = create_json_schema_kafka_io_manager(
    kafka_resource=kafka_resource,
    schema_dict={
        "type": "object",
        "properties": {
            "id": {"type": "string"},
            "timestamp": {"type": "string", "format": "date-time"}
        },
        "required": ["id", "timestamp"]
    },
    enable_schema_validation=True
)

JSON Support

Basic JSON message consumption without schema validation.

from dagster_kafka import KafkaIOManager

json_manager = KafkaIOManager(
    kafka_resource=kafka_resource,
    consumer_group_id="json-consumer",
    enable_dlq=True
)

Avro Support

Binary format with Schema Registry integration and evolution validation.

from dagster_kafka import avro_kafka_io_manager

@asset(io_manager_key="avro_kafka_io_manager")
def user_data(context, config):
    """Load user events using Avro schema with validation."""
    io_manager = context.resources.avro_kafka_io_manager
    return io_manager.load_input(
        context,
        topic="user-events",
        schema_file="schemas/user.avsc",
        validate_evolution=True
    )

Protobuf Support

High-performance binary format with full schema management.

from dagster_kafka.protobuf_io_manager import create_protobuf_kafka_io_manager

protobuf_manager = create_protobuf_kafka_io_manager(
    kafka_resource=kafka_resource,
    schema_registry_url="http://localhost:8081",
    consumer_group_id="protobuf-consumer",
    enable_dlq=True
)

Confluent Connect Integration

The Confluent Connect integration provides a complete solution for managing Kafka Connect connectors within your Dagster environment.

Connect Management

REST API Client for Kafka Connect

from dagster_kafka.connect import ConfluentConnectClient

# Create a client to interact with the Connect REST API
client = ConfluentConnectClient(base_url="http://localhost:8083")

# List available connectors
connectors = client.list_connectors()

# Get connector status
status = client.get_connector_status("my-connector")

# Create a new connector
connector_config = {
    "name": "file-source-connector",
    "config": {
        "connector.class": "org.apache.kafka.connect.file.FileStreamSourceConnector",
        "tasks.max": "1",
        "file": "/tmp/test-source.txt",
        "topic": "test-topic"
    }
}
client.create_connector(connector_config)

# Update configuration
client.update_connector_config("file-source-connector", {"tasks.max": "2"})

# Manage connector lifecycle
client.pause_connector("file-source-connector")
client.resume_connector("file-source-connector")
client.restart_connector("file-source-connector")

Connector Assets

Define Kafka Connect connectors as Dagster assets

from dagster import Definitions
from dagster_kafka.connect import ConfluentConnectResource, create_connector_asset

# Create a connector asset
source_connector = create_connector_asset(
    group_name="kafka_connect",
)

# Define your Dagster job
defs = Definitions(
    assets=[source_connector],
    resources={
        "connect": ConfluentConnectResource(
            connect_url="http://localhost:8083",
        )
    },
)

Configuration Example

ops:
  connector_asset:
    config:
      name: "mysql-source-connector"
      connector_class: "io.debezium.connector.mysql.MySqlConnector"
      config:
        tasks.max: "1"
        database.hostname: "mysql"
        database.port: "3306"
        database.user: "debezium"
        database.password: "dbz"
        database.server.id: "184054"
        database.server.name: "dbserver1"
        database.include.list: "inventory"
        database.history.kafka.bootstrap.servers: "kafka:9092"
        database.history.kafka.topic: "schema-changes.inventory"

Health Monitoring

Monitor connector health and implement auto-recovery

from dagster import job, op, sensor, SensorResult, RunRequest
from dagster_kafka.connect import ConfluentConnectResource

@sensor(
    name="connect_health_sensor",
    minimum_interval_seconds=60,
    required_resource_keys={"connect"},
)
def connector_health_sensor(context):
    """Monitor the health of Kafka Connect connectors."""
    connect = context.resources.connect
    connector_names = ["mysql-source", "elasticsearch-sink"]
    
    unhealthy_connectors = []
    
    # Check each connector
    for connector_name in connector_names:
        try:
            status = connect.get_connector_status(connector_name)
            connector_state = status["connector"]["state"]

            if connector_state != "RUNNING":
                context.log.warning(
                    f"Connector {connector_name} is in {connector_state} state"
                )
                unhealthy_connectors.append({
                    "name": connector_name,
                    "state": connector_state
                })
            
            # Also check tasks
            for task in status.get("tasks", []):
                task_state = task.get("state")
                task_id = task.get("id")
                
                if task_state != "RUNNING":
                    context.log.warning(
                        f"Task {task_id} of connector {connector_name} is in {task_state} state"
                    )
                    unhealthy_connectors.append({
                        "name": connector_name,
                        "task_id": task_id,
                        "state": task_state
                    })
        except Exception as e:
            context.log.error(f"Error checking connector {connector_name}: {e}")
    
    # If we have unhealthy connectors, trigger a remediation job
    if unhealthy_connectors:
        return RunRequest(
            run_key=f"connector_health_{context.cursor}",
            job_name="remediate_connectors_job",
            run_config={

                            "unhealthy_connectors": unhealthy_connectors
                        }
                    }
                }
            },
        )
    
    return SensorResult(
        skip_reason="All connectors healthy",
        cursor=str(context.get_current_time()),
    )

Recovery Patterns

Implement automated recovery from connector failures

from dagster_kafka.connect import ConfluentConnectClient

def advanced_recovery(client, connector_name, max_attempts=3):
    """
    Advanced recovery pattern that tries different recovery methods
    based on the nature of the failure.
    """
    for attempt in range(1, max_attempts + 1):
        try:
            # Check current status
            status = client.get_connector_status(connector_name)
            connector_state = status["connector"]["state"]
            
            if connector_state == "RUNNING":
                # Check if any tasks are failing
                tasks = status.get("tasks", [])
                failing_tasks = [
                    task for task in tasks
                    if task.get("state") != "RUNNING"
                ]
                
                if not failing_tasks:
                    return True
                
                # Restart only the failing tasks
                for task in failing_tasks:
                    task_id = task.get("id")
                    client.restart_task(connector_name, int(task_id))
            else:
                # Try different recovery strategies based on state
                if connector_state == "FAILED":
                    client.restart_connector(connector_name)
                elif connector_state == "PAUSED":
                    client.resume_connector(connector_name)
                else:
                    client.restart_connector(connector_name)
                    client.resume_connector(connector_name)
            
            # Wait for recovery to take effect and check again
            time.sleep(5)
            status = client.get_connector_status(connector_name)
            if status["connector"]["state"] == "RUNNING":
                return True
        except Exception as e:
            pass
    
    return False
