4| Apache Hadoop
The Apache Hadoop software library is a framework which allows for the distributed processing of large data sets across clusters of computers using simple programming models. The framework is composed of the following modules
- Hadoop Common: The common utilities that support the other Hadoop modules.
- Hadoop Distributed File System (HDFS): A distributed file system that provides high-throughput access to application data.
- Hadoop YARN: A framework for job scheduling and cluster resource management.
- Hadoop MapReduce: A YARN-based system for parallel processing of large data sets.
- Hadoop Ozone: An object store for Hadoop.
- Hadoop Submarine: A machine learning engine for Hadoop.
5| Apache Cassandra
Apache Cassandra is a distributed database which is highly scalable without any compromising performance. It is a perfect platform for mission-critical data as it has features such as linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure.
Some of the features of this analytics tool include
- Decentralised: There are no single points of failure as every node in the cluster is identical.
- Performant: Cassandra consistentlyoutperformspopular NoSQL alternatives in benchmarks and real applications, primarily because of fundamental architectural choices.
- Fault Tolerant: Data is automatically replicated to multiple nodes for fault-tolerance.
- Durable: Cassandra is suitable for applications that can’t afford to lose data, even when an entire data centre goes down.
Elasticsearch is a highly scalable open-source full-text search and analytics engine which allows you to store, search, and analyse big volumes of data quickly and in near real time. It is a distributed, RESTful search and analytics engine capable of solving a growing number of use cases. Some of the features of this analytics tool include
- Query: Elasticsearch lets you perform and combine many types of searches — structured, unstructured, geo, metric — any way you want.
- Analyse: Elasticsearch aggregations let you zoom out to explore trends and patterns in your data.
- Speed: Elasticsearch if incredibly fast due to the implementation of inverted indices with finite state transducers for full-text querying, BKD trees for storing numeric and geodata, and a column store for analytics.
- Fast time-to-value: Elasticsearch offers simple REST-based APIs, a simple HTTP interface, and uses schema-free JSON documents, making it easy to get started and quickly build applications for a variety of use-cases.
KNIME Analytics Platform is the leading open solution for data-driven innovation, helping you discover the potential hidden in your data, mine for fresh insights, or predict new futures. It is an enterprise-grade, open source platform which is fast to deploy, easy to scale, and intuitive to learn. KNIME Analytics Platform is easy to use and it is one of the perfect tools for a data scientist.
LUMIFY is powerful big data fusion, analysis, and visualisation platform which supports the development of actionable intelligence. The features of Lumify include
- Speed and Scale: Queries run as fast as your underlying database can support, allowing you to take advantage of your existing data infrastructure for data ingest, streaming, complex queries, etc.
- Non-Proprietary Data Storage: Lumify sits on top of standard data platforms and fits into your analytic eco-system. Lumify works with your existing data to enable sharing across your analytic tools and systems.
- Bring Your Own Analytics Capability: Lumify’s infrastructure allows you to attach new analytic tools that will work in the background to monitor changes and assist analysts as they sort through complex information.
- Real-Time and Secure Collaboration: Analysts can instantly share their workspaces with their colleagues, control individual access, and set separate controls based on security classification.
MongoDB is a document database with the scalability and flexibility which is designed for ease of development and scaling. It is open sourced and offers both a Community and an Enterprise version of the database. Some of the features include
- MongoDB stores data in flexible, JSON-like documents, meaning fields can vary from document to document and data structure can be changed over time.
- The document model maps to the objects in your application code, making data easy to work with.
- Ad hoc queries, indexing, and real-time aggregation provide powerful ways to access and analyse your data.
- MongoDB is a distributed database at its core, so high availability, horizontal scaling, and geographic distribution are built in and easy to use.
Neo4j is one of the popular graph database management systems. Neo4j’s Graph Platform is the fastest path available to operationalise enterprise analytic insights by connecting the work of big data IT to data scientists to application developers building impactful applications.
