8 Ways to Optimize AWS Glue Jobs in a Nutshell

Image
  Improving the performance of AWS Glue jobs involves several strategies that target different aspects of the ETL (Extract, Transform, Load) process. Here are some key practices. 1. Optimize Job Scripts Partitioning : Ensure your data is properly partitioned. Partitioning divides your data into manageable chunks, allowing parallel processing and reducing the amount of data scanned. Filtering : Apply pushdown predicates to filter data early in the ETL process, reducing the amount of data processed downstream. Compression : Use compressed file formats (e.g., Parquet, ORC) for your data sources and sinks. These formats not only reduce storage costs but also improve I/O performance. Optimize Transformations : Minimize the number of transformations and actions in your script. Combine transformations where possible and use DataFrame APIs which are optimized for performance. 2. Use Appropriate Data Formats Parquet and ORC : These columnar formats are efficient for storage and querying, signif

4 Top Python Oops Concepts Simplify Your Coding

Oops concepts in Python explained in this post. Python supports Encapsulation, Inheritance, Abstraction, Polymorphism and Dynamic binding. These simplify your coding effort. I have given examples on Python Oops ( Object oriented) concepts.

Python Oops (Object oriented) Concepts

  1. Encapsulation
  2. Data hiding and abstraction
  3. Inheritance
  4. Polymorphism (overloading/overriding)
The fifth Python special property is Dynamic binding.

#1 Python Oops Encapsulation

Wrapping of data and functions in a single unit is called Encapsulation.

Encapsulation

#2 Python Oops Data Hiding and abstraction

User program refers to methods from an object is called abstraction. Keeping all the methods under one object called data hiding.

Abstraction

#3 Python Oops Inheritance

Inhering properties means, referring property of an object of a class from an Object of the other Class.

Inheritance

#4 Python Oops Polymorphism

Poly means many. The definition of one function can use for many. 

The best example is the "+" operator. You can use it for the addition of numbers, and concatenate of String. 

Polymorphism

#5 Dynamic Binding

Dynamically you can call one procedure during the execution of the main program is called Dynamic binding. 

Dynamic Binding
