Apache Hadoop Ozone is a distributed key-value store that can manage both small and large files alike. Ozone was designed to address the scale limitations of HDFS with respect to small files. HDFS is designed to store large files and the recommended number of files on HDFS is 300 million for a Namenode, and doesn’t scale well beyond this limit.
Lambdas are a powerful feature of the Ruby language. They allow you to wrap logic and data into a portable package. In this post, we’ll cover how and when to use lambdas. You'll also learn about the difference between lambdas and Procs, and the performance profile of lambda functions. The code examples have been tested with 2.6 and 2.7 and should work with most modern Rubys.
Nowadays, the term ‘remote debugging’ instills fear into even the bravest of dev hearts. Palms sweaty, knees weak, and arms ready (to code) they dive into what they’re sure will end in much pain and possibly a few broken pieces of code. This scenario and these feelings are common to devs everywhere, where many opt to take the trusted path of debugging on their *own* machines.

The first thing that comes to mind when talking about synergy is how 2+2=5. Being the writer that he is, Mark Twain described it a lot more eloquently as “the bonus that is achieved when things work together harmoniously”. There is a multitude of product and business examples to illustrate the point and I particularly like how car manufacturers can bring together relatively small engines to do big things.
Every time you write another piece of code that picks up data from an FTP server, a small piece of you dies. As a developer in the data space, you know what we’re talking about. 80% of your time can be taken by building and improving the environment and tools, maintenance tasks, and pieces of functionality. That's simply too much time dedicated away from tackling more important issues.
