Apache Cassandra was initially built by Facebook for their own servers and services, using principles developed by Google and Amazon for BigTable and DynamoDB. Currently the project was donated to the Apache Foundation who continues to developed it...
Apache HBase was modeled after Google's internal BigTable database system and was built atop the famous Apache Hadoop data processing framework and distributed computing engine. Because it was built on Hadoop, some of its cool features are also inherited...
Apache Ambari allows database administrators to install, manage and monitor Hadoop clusters. Collecting metrics is done via Ganglia, while email alerts are sent out via Nagios. Amabari is basically a Web-based administration GUI for Hadoop, a tool that...
Apache Derby is one of the first database engines the Apache Software foundation hosted under its umbrella before big names like Yahoo's Hadoop, Facebook's Cassandra, or IBM's CouchDB were also donated to it. Coded from the beginning to...
Apache MetaModel supports most of the major database systems around and is focused on providing the be-all end-all interface for running database operations in Java.Using MetaModel reduces the learning curve needed when working with multi-database...
A data warehouse system is a database used for reporting and data analysis. Apache Tajo is the implementation of this concept, but specifically tailored to work with Hadoop, a powerful NoSQL database developed by Yahoo and currently managed by the Apache...
Apache Drill was created to allow developers to query up to 10,000 servers and handle petabytes of query data within seconds. Drill is Apache's response to Google's Dremel package, providing an open source solution for running large data...
Apache Parquet is a "columnar" data storage format that was specifically created for the Apache Hadoop family of projects. Parquet is recommended to be used with large data, mainly because it uses a complex data compression system, relying on a series of...
Apache Empire-db functions like a Java ORM but it provides extra support for basic data persistence methods. This implicitly means better targeted SQL statements that provide better and more efficient query results. Empire-db is easy to use, not requiring...
Apache Gora aims at providing a common ground on which developers can create tools that can handle large quantities of information, regardless of their underlying storage unit. Gora is written in Java and was created as an alternative to other Java ORMs...
