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

Python For Loop increment Tricky Example

Here's tricky for loop example in Python. The usage of FOR LOOP is to create loops. How many times the loop will execute you may supply in the input.

My Project is to get each character from the input String. I have used for loop to achieve this. Let me explain how I did this. Explained Tricky FOR LOOP Examples.

1. Python For Loop Array


>> for value in variable

Here's an example:

>> myName = 'srinimf'

>> for value in myName
...        print(value)


The result is as follows:
s
r
i
n
i
m
f

2. Python For Loop With '1' to '10' or 'n'


for (i = 1; i <= 10; i++)
    <loop body>

This for loop is useful to create a definite-loop. The maximum number of loops here are '10'. In the body, you need to add Python logic.

This is one of the tricky and most popular examples.

3. Python For Loop a Flow Chart

Explanation:

  • The 'letter' contains Value
  • The 'stateName' can be an Array or Variable
  • After For Loop, you can use BODY statements

Summary
  1. The purpose of the for loop is to handle loops 
  2. You can unstring from the main string 
  3. You can use for loop with range() built-in function 
  4. You can handle program logic in the For Loop
