Spark Overview
- Spark is an open-source, distributed compute engine for processing large datasets.
- It offers higher-level APIs and supports multiple languages like SQL, Python, and R.
Spark and Machine Learning
- Spark provides a data set framework for distributed processing, including machine learning.
- It can integrate with other machine learning frameworks like Pandas, Scikit-learn, TensorFlow, and Keras.
Data Parallelism in Spark
- Spark excels at data parallel processing, where tasks are independent and work on different data subsets.
- This approach is efficient for many tasks, but deep learning presents scaling challenges due to its inherent dependencies.
