Close-up of database servers Breaking Down Apache’s Hadoop Distributed File System

Apache Hadoop is a framework for big data. One of its main components is HDFS, Hadoop Distributed File System, which stores that data. You might expect that a storage framework that holds large quantities of data requires state-of-the-art infrastructure for a file system that does not fail, but quite the contrary is true.

Shelves storing many books and files Comparing Apache Hadoop Data Storage Formats

Apache Hadoop can store data in several supported file formats. To decide which one you should use, analyze their properties and the type of data you want to store. Let's look at query time, data serialization, whether the file format is splittable, and whether it supports compression, then review some common use cases.

Columns of the Parthenon Benefits of Using Columnar Storage in Relational Database Management Systems

Relational database management systems (RDBMS) store data in rows and columns. Most relational databases store data row-wise by default, but a few RDBMS provide the option to store data column-wise, which is a useful feature. Let’s look at the benefits of being able to use columnar storage for data and when you'd want to.

Apache logo Comparing Apache Sqoop, Flume, and Kafka

Apache Sqoop, Flume, and Kafka are tools used in data science. All three are open source, distributed platforms designed to move data and operate on unstructured data. Each also supports big data in the scale of petabytes and exabytes, and all are written in Java. But there are some differences between these platforms.

Hand pointing at data on a screen Should You Use XML or Protocol Buffers to Store and Exchange Data?

XML is a flexible text format used for a wide variety of applications, including data serialization and exchange of data. More recently, protocol buffers were also introduced for data exchange and data serialization. Even though their purpose is the same, these are very different technologies. Which is better for you?

Building with clouds reflected in the windows Choosing a Cloud Storage Service

When choosing storage through a managed cloud service, you should consider several factors: What type of storage is needed? What is the type of application or service? What is the scale of data? What kind of accessibility, availability, and durability do you require? All these aspects should influence your decision.
