Apache Wayang is a dataflow and distributed computing framework designed for cross-platform data processing, enabling applications to be decoupled from underlying platforms. This allows for platform-agnostic application development. Wayang's cross-platform optimizer determines the most efficient execution plan across various platforms, such as Apache Flink and Apache Spark. The primary performance challenges in cross-platform execution within Wayang include heterogeneous hardware, network latency and bandwidth, data locality, resource management, vendor-specific optimizations, and abstraction overhead. This report analyzes the performance implications of cross-platform execution in Wayang, focusing on optimization strategies for major cloud providers like AWS, Azure, and GCP, as of June 09, 2025. The key benefit of Wayang is its ability to optimize execution plans across multiple platforms, potentially leading to significant performance gains compared to single-platform execution.

General Overview of Wayang

Wayang is a system designed for cross-platform data processing, aiming to decouple applications from the underlying processing platforms. This decoupling allows users to specify applications in a platform-agnostic manner, with Wayang's cross-platform optimizer translating these logical plans into execution plans optimized for specific platforms like Apache Flink and Apache Spark. The ultimate goal is to minimize execution cost, such as runtime or monetary cost, by intelligently selecting the most efficient platform for each subtask. Wayang's optimizer considers factors like data movement costs and operator costs to determine the optimal execution plan.

Specific Performance Challenges of Cross-Platform Execution in Wayang

Several factors contribute to performance challenges in cross-platform execution within Wayang. These include:

  • Heterogeneous Hardware: Different platforms may have varying hardware capabilities, such as CPU, memory, and specialized accelerators (e.g., FPGAs), which can impact performance.
  • Network Latency and Bandwidth: Data transfer between different platforms introduces network overhead, which can significantly affect performance, especially for large datasets.
  • Data Locality: Moving data between platforms can be costly. Optimizing data locality, by keeping data close to the processing units, is crucial for performance.
  • Resource Management: Efficiently managing compute, storage, and network resources across different platforms is essential to avoid bottlenecks and ensure optimal resource utilization.
  • Vendor-Specific Optimizations: Leveraging vendor-specific features and optimizations (e.g., specialized compute instances, optimized storage) can improve performance.
  • Abstraction Overhead: The abstraction layer introduced by Wayang, while providing platform independence, can introduce overhead that needs to be mitigated.

Performance Implications of Cross-Platform Execution in Wayang


While the abstraction layer and data transfer inherent in cross-platform execution can introduce overhead, Wayang's optimizer aims to mitigate this by selecting the most efficient execution plan. This can potentially lead to faster execution times compared to single-platform approaches. The optimizer considers factors like data movement costs and operator costs to determine the optimal execution plan.

Overview of Major Cloud Providers and Relevant Services

The major cloud providers, including AWS, Azure, and GCP, offer various services relevant to distributed computing.

  • AWS: AWS offers FPGAs and tools like CloudWatch Logs and X-Ray.
  • Azure: Azure offers FPGAs and Azure Machine Learning.
  • GCP: GCP offers FPGAs.


Optimization Strategies for Wayang on AWS

To optimize Wayang on AWS, several strategies can be employed:

  • Leverage AWS F1 Instances: Utilize AWS F1 instances, which are FPGA-accelerated, for tasks that can benefit from hardware acceleration.
  • Optimize Data Locality: Employ AWS services like S3 for data storage and consider using AWS Direct Connect for faster data transfer between on-premises and the cloud.
  • Resource Management: Utilize AWS services like EC2 for compute, and optimize instance types based on workload requirements. Use Auto Scaling to dynamically adjust resources.
  • Monitoring and Logging: Integrate with AWS CloudWatch Logs and X-Ray for monitoring and performance analysis.


Optimization Strategies for Wayang on Azure

Optimizing Wayang on Azure involves similar strategies:

  • Utilize FPGA-Accelerated Instances: Leverage Azure's FPGA-accelerated instances for tasks that can benefit from hardware acceleration.
  • Optimize Data Locality: Use Azure Blob Storage for data storage and Azure ExpressRoute for faster data transfer.
  • Resource Management: Utilize Azure Virtual Machines for compute and Azure Virtual Network for network configuration. Implement Azure Monitor for resource monitoring.
  • Integration with Azure Machine Learning: Integrate with Azure Machine Learning for machine learning tasks.


Optimization Strategies for Wayang on GCP

Optimization strategies for Wayang on GCP include:

  • Utilize FPGA-Accelerated Instances: Leverage GCP's FPGA-accelerated instances for tasks that can benefit from hardware acceleration.
  • Optimize Data Locality: Use Google Cloud Storage for data storage and Google Cloud Interconnect for faster data transfer.
  • Resource Management: Utilize Google Compute Engine for compute and Google Kubernetes Engine (GKE) for container orchestration. Implement Google Cloud Monitoring for resource monitoring.

Beyond Ctrl+F - Use LLM's For PDF Analysis

By
PDFs are everywhere, seemingly indestructible, and present in our daily lives at all thinkable and unthinkable positions. We've all got mountains of them, and even companies shouting about "digital transformation" haven't managed to escape their clutches. Now, I'm a product guy, not a document management guru. But I started thinking: if PDFs are omnipresent in our existence, why not throw some cutting-edge AI at the problem? Maybe Large Language Models (LLMs) and Retrieval Augmented Generation (RAG) could be the answer. Don't get me wrong, PDF search indexes like Solr exist, but they're basically glorified Ctrl+F. They point you to the right file, but don't actually help you understand what's in it. And sure, Microsoft Fabric's got some fancy PDF Q&A stuff, but it's a complex beast with a hefty price tag. That's why I decided to experiment with LLMs and RAG. My idea? An intelligent knowledge base built on top of our existing P...

Deal with corrupted messages in Apache Kafka

By
Under some strange circumstances, it can happen that a message in a Kafka topic is corrupted. This often happens when using 3rd party frameworks with Kafka. In addition, Kafka < 0.9 does not have a lock on Log.read() at the consumer read level, but does have a lock on Log.write(). This can lead to a rare race condition as described in KAKFA-2477 [1]. A likely log entry looks like this: ERROR Error processing message, stopping consumer: (kafka.tools.ConsoleConsumer$) kafka.message.InvalidMessageException: Message is corrupt (stored crc = xxxxxxxxxx, computed crc = yyyyyyyyyy Kafka-Tools Kafka stores the offset of each consumer in Zookeeper. To read the offsets, Kafka provides handy tools [2]. But you can also use zkCli.sh, at least to display the consumer and the stored offsets. First we need to find the consumer for a topic (> Kafka 0.9): bin/kafka-consumer-groups.sh --zookeeper management01:2181 --describe --group test Prior to Kafka 0.9, the only way to get this in...

What Makes You The Number 1 Product Manager?

By
Amazon often does this thing where they start with the customer instead of just coming up with a product and then trying to figure out how to sell it. They call it " working backwards. " This strategy totally works for any product decisions, but it's especially important when they're making something new. The Press Release Exercise When it comes to launching new stuff, product managers usually start by writing a press release for customers. This press release is all about their pain points, how current solutions fall short, and how the new product is going to crush it. If the benefits don't get customers excited, the product manager needs to keep tweaking the press release until it sounds super awesome. It's way easier and cheaper to make changes to a press release than it is to change the product itself. Here’s a template I use to describe a new service or product: Main heade r: The product name anyone directly understands, like “Ultra-compact power charger” ...
