11. Spark SQL queries: Understand Spark SQL's capabilities for executing SQL queries on Dataframes.

Advanced PySpark Concepts

12. Infer Schema vs Provide Schema: Learn how to handle data schemas in PySpark.
13. Filter rows, count, distinct, duplicate, sort, order By, Group By: Perform common data manipulation and aggregation operations on Dataframes.
14. UDFs (User-Defined Functions): Create custom functions for specific data processing needs.

Machine Learning with PySpark

15. Collaborative filtering: Understand and implement recommendation systems using the ALS (Alternating Least Squares) model.
16. ALS model: Dive deep into how to use the ALS algorithm for building a recommender system in PySpark.

Streaming Data with Spark

17. Spark Streaming: Learn how to process real-time data streams using Spark Streaming.
18. Word Count example: Build a simple Spark Streaming application to count word frequencies.

ETL Pipeline and AWS Services

19. ETL pipeline: Design and implement an Extract, Transform, Load (ETL) process for data integration.
20. Change Data Capture (CDC): Understand CDC and how it can be used to capture changes in the database.
21. Replication: Learn about data replication strategies between different systems or environments.

AWS Services Integration

22. AWS Glue Job: Use AWS Glue for ETL tasks and automate data preparation jobs.
23. Lambda Function: Write serverless functions on AWS to perform specific tasks in response to events.
24. RDS: Set up a relational database service (RDS) on AWS for structured storage and querying.
25. S3 Bucket: Use Amazon S3 for scalable object storage.
26. Data Migration Service (DMS): Migrate databases with minimal downtime using AWS Database Migration Service.
27. PgAdmin: Manage PostgreSQL databases using PgAdmin, and integrate them with PySpark for analysis.

Practical Application and Projects

28. Spark Shell Job: Write and execute Spark jobs from the Spark shell for quick testing and development.
29. Full Load Pipeline: Create a pipeline to load data into AWS, transform it as needed, and make it available for analysis or machine learning tasks.
30. Change Data Capture Pipeline: Develop a CDC pipeline to continuously capture changes in data and respond accordingly.

Real-World Implementation

31. Capstone Project: Apply all the learned concepts in a comprehensive capstone project that showcases your ability to handle real-world Big Data problems using PySpark and AWS.

By following this structured approach, you can systematically learn and apply PySpark with AWS, ensuring that you gain both theoretical knowledge and practical skills necessary for handling large-scale data processing tasks effectively.
