Description
As part of this course, you will learn all the Data Engineering Essentials related to building Data Pipelines using SQL, Python as Hadoop, Hive, or Spark SQL as well as PySpark Data Frame APIs. You will also understand the development and deployment lifecycle of Python applications using Docker as well as PySpark on multinode clusters. You will also gain basic knowledge about reviewing Spark Jobs using Spark UI.
About Data Engineering
Data Engineering is nothing but processing the data depending on our downstream needs. We need to build different pipelines such as Batch Pipelines, Streaming Pipelines, etc as part of Data Engineering. All roles related to Data Processing are consolidated under Data Engineering. Conventionally, they are known as ETLÂ Development, Data Warehouse Development, etc.
Here are some of the challenges the learners have to face to learn key Data Engineering Skills such as Python, SQL, PySpark, etc.
- Having an appropriate environment with Apache Hadoop, Apache Spark, Apache Hive, etc working together.
- Good quality content with proper support.
- Enough tasks and exercises for practice
This course is designed to address these key challenges for professionals at all levels to acquire the required Data Engineering Skills (Python, SQL, and Apache Spark).
- Set up an Environment to learn Data Engineering Essentials such as SQL (using Postgres), Python, etc.
- Setup required tables in Postgres to practice SQL
- Writing basic SQLÂ Queries with practical examples using WHERE, JOIN, GROUPÂ BY, HAVING, ORDERÂ BY, etc
- Advanced SQLÂ Queries with practical examples such as cumulative aggregations, ranking, etc
- Scenarios covering troubleshooting and debugging related to Databases.
