What are the performance implications of cross-platform execution within Wayang, and how can these be optimized for each cloud provider?
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....
