Spark Structured Streaming with continuous web data ingestion
Blog post from Bright Data
Apache Spark Structured Streaming is a robust stream processing engine that operates on top of the Spark SQL engine, processing live data streams as continuously appended tables. Unlike its predecessor, Spark Streaming, which uses DStreams and RDDs, Structured Streaming employs DataFrame and Dataset APIs, facilitating event-time windowing, fault tolerance through checkpointing, and seamless integration of streaming and static data. The article highlights the integration of Bright Data’s SERP API with Spark Structured Streaming to build a PySpark pipeline capable of ingesting live web search data. This integration leverages Bright Data's infrastructure to fetch search engine results pages (SERPs) without the need for managing scraping complexities such as proxies or CAPTCHAs. The pipeline uses Spark's micro-batch model to periodically retrieve and transform SERP data, enabling use cases like keyword rank tracking, news aggregation, and competitive monitoring. The tutorial demonstrates building a continuous ingestion pipeline, emphasizing fault tolerance and scalability, and suggests deploying it on platforms like Databricks for production-grade applications.
