  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

While the debate over the value of a computer science degree rages on, these programming leaders emphasize the importance of a well-rounded education, with plenty of time spent studying subjects beyond the console. The biggest challenges in life do not have technical fixes," Eich says, "so it's important to study history, literature, art, and other kinds of human knowledge than anything to do with computers. Hickey agrees, placing programming into a broader perspective. "Programming is a very new endeavor in the historical scheme of things," he says. "One shouldn't presume that we understand how best to pursue it. 1# Tips to become a programmer " Instead, Hickey suggests pursuing other educational interests to help understand the kinds of problems programming can solve."The best programmers are those that can understand, communicate about, and solve problems in the domains they are in," he says. "Software is just a tool for t
