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

PhoneGap platform top details you need to develop mobile apps: part-1

There are many smartphone platforms on the market: Android, iPhone, BlackBerry, Nokia, the Windows 7 Phone, and WebOS. Newer platforms are on the rise as well, such as Samsung's Bada and Meego.

Why PhoneGap You Need


The development of mobile applications increasing day by day, so you need one solution. That is single platform.

History of Operating system


  • In the year 2000, we saw a similar situation in the desktop world. We had Microsoft Windows, Apple's Mac, and various versions of Linux and UNIX. 
  • At that time, it was difficult to build products that would run on all these platforms. The resulting fragmentation was often solved via in-house solutions by building frameworks in C++, with Operating System (OS)-specific modules abstracted.
  • Fortunately, Sun's Java came to the rescue and provided us with a common platform on which to build. With Java's build-once-and-run-anywhere strategy, building desktop products had become a breeze.
  • Between 2004 and 2008, the developer community saw a different kind of fragmentation; this time, it took place in the browser world. It was a fragmentation involving the very popular Internet Explorer 6 vs. Firefox and Safari—then, Chrome and other browsers came out of the woodwork, causing further fragmentation.

Story of PhoneGap

Many companies that want to develop mobile applications for multiple platforms either have their own web services or rely on other web services. While PhoneGap can work for standalone mobile applications, it is very well-suited for mobile applications that make use of web services. 

Web service is a technology useful for machine to machine communication.

The reason for this is that PhoneGap applications are primarily web applications that are augmented with device features. Think about a Flickr web application that has access to a device's camera or Google Maps application, which, in turn, has access to a GPS. Another example is Foursquare, which has access to your GPS, as well as your phone's address book.

Single platform and you can develop any app.

This more or less means that a majority of PhoneGap-based applications will access web services using JavaScript. This makes it important for developers using PhoneGap to have a handle on using web services.
