8 Ways to Optimize AWS Glue Jobs in a Nutshell

  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

How to Find Folder Space in Linux Easily

Here's an example that shows how to use find command to get directory utilized space in Linux. Many of a time during production support, or when crontab jobs failed, the reasons behind is space shortage of a directory. The find is handy you can use to get utilized space of a directory. That helps you to delete unnecessary files (that actually make some space). Linux find command Here's the find command that I  have used in our project . You will find here the detailed explanation of this command and how to use it. find  /home/srini -xdev -ls | sort +6rn | head -20 Part#1: Directory path In the first part,  after the find you need to give the directory's path for which  folder you are going to find  space. Part#2: Option -xdev The second part is  -xdev , which gives the space usage of all the subdirectories. Part#3: Option -ls The next part is the -ls option that provides a sorted list of all the subdirectories.  Part#4: Sort command Then, the sort command sorts based on the
