Apache Kafka is a distributed streaming platform that enables real-time data pipelines and streaming applications. It is designed for high throughput and fault tolerance, making it ideal for applications that require processing and analyzing continuous streams of data.

7. Matplotlib

Description:
Matplotlib is a comprehensive plotting library for Python that allows users to create static, animated, and interactive visualizations in a variety of formats. It’s widely used for data analysis and scientific computing.

8. Seaborn

Description:
Seaborn is a statistical data visualization library based on Matplotlib. It provides a high-level interface for creating attractive and informative graphics, simplifying the process of creating complex visualizations.

9. Spark MLlib:

Description: Spark MLlib is a scalable machine learning library integrated with Apache Spark, designed to handle large-scale data processing efficiently. It offers a variety of algorithms and utilities for classification, regression, clustering, collaborative filtering, and dimensionality reduction.

10. GraphX:

Description: A component of Spark for graph processing and graph-structured data analytics. GraphX is Apache Spark’s library for graph analytics, providing a unified API for graph-parallel computation. It enables users to analyze, transform, and process graph-structured data effectively.
