PySpark Training and Certification in Kraków, Poland

PySpark training introduces learners to the power of Apache Spark for processing large-scale data using Python. It covers core concepts such as Resilient Distributed Datasets (RDDs), DataFrames, and SparkSQL, providing the foundation for data manipulation and analysis. Participants gain hands-on experience in working with PySpark for both batch and real-time data processing, leveraging its scalability and speed. The training also explores advanced topics like machine learning with MLlib, graph processing with GraphX, and performance optimization techniques. By completing this course, professionals can apply PySpark to handle complex big data tasks and build efficient data pipelines for analytics.
