3. Confluent: Managed Kafka for Enterprises
Overview: Confluent offers a managed Kafka service with additional features like schema registry and advanced monitoring.
- Scalability: Simplifies Kafka’s scaling for enterprise-grade applications. You need a DevOps team to handle maintenance and scaling.
- Observability: Provides monitoring dashboards but at an enterprise cost.
- Code Maintainability: Same Java/Scala limitations as Kafka.
- Error Handling: Easier than self-managed Kafka.
- Latency: While Confluent offers low latency similar to Kafka, achieving optimal performance requires extensive configuration of partitions, replication, and brokers.
- Time to Market: Faster than self-managed Kafka but still not quick enough. It still requires you to understand and oversee the future application architecture.
4. Apache Flink: Advanced Real-Time Processing
Overview: Apache Flink is built for complex data processing and integrates well with Kafka. However, it’s more suited for advanced use cases requiring heavy data transformations.
- Scalability: Scales well but demands advanced setup and tuning.
- Observability: Lacks native observability tools; requires integration with external monitoring systems.
- Code Maintainability: Requires significant development expertise in Java/Scala.
- Error Handling: Custom solutions are needed for error recovery.
- Latency: Low latency but requires manual optimization.
- Time to Market: Significant effort is required for deployment and scaling. Because Apache Kafka and Apache Flink work incredibly well together to power real-time data streaming pipelines. So, oftentimes you need to use and manage both services.
5. Amazon MSK: Another managed Kafka Service in AWS
Overview: Amazon MSK offers a managed Kafka service that simplifies deployment on AWS but lacks integrated data transformation tools. While Amazon MSK efficiently handles data ingestion, it lacks native tools for real-time data transformation and enrichment. Users must rely on separate processing tools like Amazon Managed Service for Apache Flink or AWS Lambda, which require additional setup, integration, and management. This lack of built-in transformation capability complicates the pipeline and often leads to performance issues due to the added extra layers.
- Scalability: Scales well on AWS infrastructure but needs manual partition adjustments for performance optimization.
- Observability: Limited to AWS CloudWatch unless extended with third-party tools.
- Code Maintainability: Same Java/Scala dependencies as Kafka.
- Error Handling: Limited support for automatic error recovery.
- Latency: Suffers from added layers when combined with separate processing tools.
- Time to Market: Faster than self-hosted Kafka but still requires setup and integration.
6. Google DataFlow: A Stream Processing Tool with Google Cloud Integration
Overview: Google DataFlow integrates well with Google Cloud services (for example, using it with Pub/Sub service) and supports batch and streaming pipelines. You can build your pipelines in low-code UI too.
- Scalability: Scales across multiple nodes but requires careful configuration to avoid bottlenecks. For scalability, Dataflow might run pipeline stages in parallel across multiple workers. Dataflow uses units called “keys” for parallel processing, you need to define keys correctly. Without enough keys, bottlenecks can develop, slowing down data flow and reducing efficiency. These issues make it challenging to rely on DataFlow for seamless, high-speed real-time streaming.
- Observability: Limited insights into worker performance without additional monitoring.
- Code Maintainability: Supports Python and SQL but can become complex with advanced pipelines.
- Error Handling: Unhealthy workers can stall pipelines, requiring manual intervention. Real-time streaming pipelines with Google DataFlow always require stable and healthy worker nodes. However, in DataFlow, unhealthy workers can cause the pipeline to slow down or appear stuck. It requires you to constantly monitor memory utilization and error logs to identify which workers are not functioning well.
- Latency: Can lag during high loads due to processing bottlenecks.
- Time to Market: Longer setup time compared to tools like GlassFlow.
7. Databricks: Unified Platform for Batch and Streaming with High Costs
Overview: Databricks provides Delta Live Tables for building streaming data pipelines with a declarative approach. However, using Databricks for streaming can be costly. It’s based on Apache Spark’s structured streaming engine, which, while powerful, has a high cost of storage when using structured streaming. Especially, if you want to run a 24/7 streaming job. Of course, you can always use Databricks cost reduction cheat sheet to make it not super expensive.
- Scalability: Excellent scalability but comes at a high cost.
- Observability: Robust monitoring tools for pipelines but require additional setup.
- Code Maintainability: Python and SQL support makes it easier to manage compared to Kafka.
- Error Handling: Handles errors efficiently but requires tuning for 24/7 streaming jobs.
- Latency: Structured Streaming can introduce latency for continuous jobs.
- Time to Market: Faster for batch jobs but slower for real-time use cases due to high setup costs.
