Apache Hadoop Ozone was designed to address the scale limitation of HDFS with respect to small files and the total number of file system objects. On current data center hardware, HDFS has a limit of about 350 million files and 700 million file system objects. Ozone’s architecture addresses these limitations[4]. This article compares the performance of Ozone with HDFS, the de-facto big data file system.

Solving a problem programatically often involves grouping data items together so they can be conveniently operated on or copied as a single unit – the items are collected in a data structure.

Each has strengths and weaknesses and is more or less suitable for a specific use case.

I love traveling to Barcelona for conferences. Between Gaudi’s architecture and tech architectures, there’s really not much more I can ask for.

According to Wikipedia, “Functional testing is a quality assurance process and a type of black-box testing that bases its test cases on the specifications of the software component under test. Functions are tested by feeding them input and examining the output, and the internal program structure is rarely considered.” Functional testing is a Black Box technique in which the output is validated against the input provided to the application.

AWS Lambda is a serverless compute service that runs your code in response to events and automatically manages the underlying compute resources for you. Amazon API Gateway is a managed service that allows developers to define the HTTP endpoints of a REST API and connect those endpoints with the corresponding backend business logic.
