  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

RSA token and Entrust token both are public-key providers. In the process of identity management, both play a typical role.  Once you register with token providers, you will get one private Token. You need to enter both a private PIN and a Token number displayed on the App. These tokens are mandatory for financial projects . Else they have to pay hefty penalties by non following compliance. Also, check  AWS Encryption Top Supported Features . Entrust Token. Entrust provides both private and public keys to access secure domains. Time-based OATH TOTP algorithm (OT version). Supports PVN validation. First, you need to enter the private PIN and then Token. RSA Token. RSA provides both private and public keys. Both the keys you need to enter to log in to financial or secure servers. Identity management. Both Soft token and Hard tokens available. With the registered token, you can access multiple devices. Finger Print based tokens available Face recognition Tokens available. RSA uses a machi
