Why I’m Loving Spark 4’s Python Data Source (with Direct Arrow Batches)
Why I’m Loving Spark 4’s Python Data Source (with Direct Arrow Batches) TL;DR: Apache Spark 4 lets you build first-class data sources in pure Python. If your reader yields Arrow RecordBatch objects, Spark ingests them with reduced Python↔JVM serialization overhead. I used this to ship a ROOT data format reader for PySpark. A PySpark reader

Can High Energy Physics Analysis Profit from Apache Spark APIs?
Can High Energy Physics Analysis Profit from Apache Spark APIs? We are in a golden age for distributed data processing, with an abundance of tools and solutions emerging from industry and open source. High Energy Physics (HEP) experiments at the LHC stand to profit from all this progress, as they are data-intensive operations with several

Machine Learning Pipelines for High Energy Physics Using Apache Spark with BigDL and Analytics Zoo
Machine Learning Pipelines for High Energy Physics Using Apache Spark with BigDL and Analytics Zoo Topic: This post describes a data pipeline for a machine learning task of interest in high energy physics: building a particle classifier to improve event selection at the particle detectors. The pipeline is built using tools from the “Big Data
