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

  • Provides a debugger and complete integrated development environment(IDE) with COBOL. 
  • Provides IP tools like Power COBOL (These tools help Developer to build Windows biased GUI Apps) and PowerBsort. 
  • It supports databases like Microsoft SQL Server, Oracle, and Pervasive SQL. 
  • Claims to support native SQL Calls “EXEC SQL” within Net COBOL. 
  • It supports Betrive Files as well. 
  • Support Both Modern IDE (Eclipse Plugins for Linux and VS IDE plug-in for Windows) 
  • Linux Version of Net COBOL also supports JAVA, C, C++, and Python. 
  • Windows Version of Net COBOL also supports .net. 
  • It also supports Unicode Code set. 
  • It also supports Object-Oriented COBOL.
Platforms for NetCOBOL:
  1. Windows – Net COBOL for Windows
  2. Linux(RHEL6) - Net COBOL for Linux

  4. Cloud (Microsoft’s Azure) - COBOL for .net

Features

  1. NetCOBOL complies with International Standard, industry standard specifications, and ordinary standard specifications, which enables stable operation and expansion of key system for the future. Existing skills on COBOL and know-how of mainframes help you a lot.
  2. "NetCOBOL Studio," a COBOL development environment based on Eclipse which is an open-source integrated development environment, has been built into NetCOBOL for Windows, and Microsoft "Visual Studio" has been built into NetCOBOL for .NET as a development environment for .NET Framework. 
  3. COBOL Integrated Development Environment (IDE) allows the improvement of efficiency of the whole development process including design, programming, testing, and maintenance. It enables program development linking with the latest technologies from batch to Web applications. 
  4. NetCOBOL is suitable to use with the latest technologies such as .NET, Java, and XML.
  5. The "PowerBSORT" speeds up sorting and merging the data.
