Apache Phoenix
Apache Phoenix is an open source, massively parallel, relational database engine supporting OLTP for Hadoop using Apache HBase as its backing store. Phoenix provides a JDBC driver that hides the intricacies of the NoSQL store enabling users to create, delete, and alter SQL tables, views, indexes, and sequences; insert and delete rows singly and in bulk; and query data through SQL. Phoenix compiles queries and other statements into native NoSQL store APIs rather than using MapReduce enabling the building of low latency applications on top of NoSQL stores. History Phoenix began as an internal project by the company salesforce.com out of a need to support a higher level, well understood, SQL language. It was originally open-sourced on GitHub on 28 Jan 2014 and became a top-level Apache project on 22 May 2014. Apache Phoenix is included in the Cloudera Data Platform 7.0 and above, Hortonworks distribution for HDP 2.1 and above, is available as part of Cloudera labs, and is part of th ...

Apache Software Foundation
The Apache Software Foundation (ASF) is an American nonprofit corporation (classified as a 501(c)(3) organization in the United States) to support a number of open source software projects. The ASF was formed from a group of developers of the Apache HTTP Server, and incorporated on March 25, 1999. As of 2021, it includes approximately 1000 members. The Apache Software Foundation is a decentralized open source community of developers. The software they produce is distributed under the terms of the Apache License and is a non-copyleft form of free and open-source software (FOSS). The Apache projects are characterized by a collaborative, consensus-based development process and an open and pragmatic software license, which is to say that it allows developers who receive the software freely, to re-distribute it under nonfree terms. Each project is managed by a self-selected team of technical experts who are active contributors to the project. The ASF is a meritocracy, implying t ...

NoSQL
A NoSQL (originally referring to "non- SQL" or "non-relational") database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases. Such databases have existed since the late 1960s, but the name "NoSQL" was only coined in the early 21st century, triggered by the needs of Web 2.0 companies. NoSQL databases are increasingly used in big data and real-time web applications. NoSQL systems are also sometimes called Not only SQL to emphasize that they may support SQL-like query languages or sit alongside SQL databases in polyglot-persistent architectures. Motivations for this approach include simplicity of design, simpler "horizontal" scaling to clusters of machines (which is a problem for relational databases), finer control over availability and limiting the object-relational impedance mismatch. The data structures used by NoSQL databases (e.g. key–value pair, wide column, graph, or document ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Software
Free software or libre software is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program.Selling Free Software (gnu.org) Computer programs are deemed "free" if they give end-users (not just the developer) ultimate control over the software and, subsequently, over their devices. The right to study and modify a computer program entails that |
Apache Hadoop
Apache Hadoop () is a collection of open-source software utilities that facilitates using a network of many computers to solve problems involving massive amounts of data and computation. It provides a software framework for distributed storage and processing of big data using the MapReduce programming model. Hadoop was originally designed for computer clusters built from commodity hardware, which is still the common use. It has since also found use on clusters of higher-end hardware. All the modules in Hadoop are designed with a fundamental assumption that hardware failures are common occurrences and should be automatically handled by the framework. The core of Apache Hadoop consists of a storage part, known as Hadoop Distributed File System (HDFS), and a processing part which is a MapReduce programming model. Hadoop splits files into large blocks and distributes them across nodes in a cluster. It then transfers packaged code into nodes to process the data in parallel. This a ...

Hortonworks
Hortonworks was a data software company based in Santa Clara, California that developed and supported open-source software (primarily around Apache Hadoop) designed to manage big data and associated processing. Hortonworks software was used to build enterprise data services and applications such as IoT (connected cars, for example), single view of X (such as customer, risk, patient), and advanced analytics and machine learning (such as next best action and realtime cybersecurity). Hortonworks had three interoperable product lines: * Hortonworks Data Platform (HDP): based on Apache Hadoop, Apache Hive, Apache Spark * Hortonworks DataFlow (HDF): based on Apache NiFi, Apache Storm, Apache Kafka * Hortonworks DataPlane services (DPS): based on Apache Atlas and Cloudbreak and a pluggable architecture into which partners such as IBM can add their services. In January 2019, Hortonworks completed its merger with Cloudera. History Hortonworks was formed in June 2011 as an independen ...

Cloudera
Cloudera, Inc. is an American software company providing enterprise data management systems that make significant use of Apache Hadoop. As of January 31, 2021, the company had approximately 1,800 customers. History Cloudera, Inc. was formed on June 27, 2008, by Christophe Bisciglia (from Google), Amr Awadallah (from Yahoo!), Jeff Hammerbacher (from Facebook), and Mike Olson (from Oracle). Awadallah oversaw a business unit performing data analysis using Hadoop while at Yahoo!; Hammerbacher used Hadoop to develop some of Facebook's data analytics applications; and Olson formerly served as the CEO of Sleepycat Software, the company that created Berkeley DB. The four were joined in 2009 by Doug Cutting, a co-founder of Hadoop. In March 2009, Cloudera released a commercial distribution of Hadoop, in conjunction with a $5 million investment led by Accel Partners. This was followed by a $25 million funding round in October 2010, a $40M funding round in November 2011, and a $160M fundi ...

MapReduce
MapReduce is a programming model and an associated implementation for processing and generating big data sets with a parallel, distributed algorithm on a cluster. A MapReduce program is composed of a ''map'' procedure, which performs filtering and sorting (such as sorting students by first name into queues, one queue for each name), and a ''reduce'' method, which performs a summary operation (such as counting the number of students in each queue, yielding name frequencies). The "MapReduce System" (also called "infrastructure" or "framework") orchestrates the processing by marshalling the distributed servers, running the various tasks in parallel, managing all communications and data transfers between the various parts of the system, and providing for redundancy and fault tolerance. The model is a specialization of the ''split-apply-combine'' strategy for data analysis. It is inspired by the map and reduce functions commonly used in functional programming,"Our abstraction is in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
