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

8 Popular Encryption Methods Real Usage

The process of replacing original data with special-characters is called an Encryption. A highly secured server handles the encryption and Decryption. You need a private key to decrypt the data. Else, you cannot decrypt the data. Private keys are two types. The sender uses one private key and the receiver uses one other private key. I have given in this post about 8 encryption methods.

Classic Cipher. The best example is this kind of algorithm was used in world war -II communication machines. 2. Random Key Generations. One kind of security. They use an algorithm that sends random numbers. People use that number as a password.  3. RSA Token. Every 30 seconds a token is generated. Mostly people use for financial ap
