Introduction to Hbase Schema Design
Introduction to HBase Schema Design AmANDeeP KHURANA Amandeep Khurana is The number of applications that are being developed to work with large amounts a Solutions Architect at of data has been growing rapidly in the recent past . To support this new breed of Cloudera and works on applications, as well as scaling up old applications, several new data management building solutions using the systems have been developed . Some call this the big data revolution . A lot of these Hadoop stack. He is also a co-author of HBase new systems that are being developed are open source and community driven, in Action. Prior to Cloudera, Amandeep worked deployed at several large companies . Apache HBase [2] is one such system . It is at Amazon Web Services, where he was part an open source distributed database, modeled around Google Bigtable [5] and is of the Elastic MapReduce team and built the becoming an increasingly popular database choice for applications that need fast initial versions of their hosted HBase product. random access to large amounts of data . It is built atop Apache Hadoop [1] and is [email protected] tightly integrated with it . HBase is very different from traditional relational databases like MySQL, Post- greSQL, Oracle, etc . in how it’s architected and the features that it provides to the applications using it . HBase trades off some of these features for scalability and a flexible schema . This also translates into HBase having a very different data model . Designing HBase tables is a different ballgame as compared to relational database systems . I will introduce you to the basics of HBase table design by explaining the data model and build on that by going into the various concepts at play in designing HBase tables through an example . -

Outline: Combining Brainstorming Deliverables Table of Contents 1. Introduction and Definition 2. Reference Architecture and Taxonomy 3. Requirements, Gap Analysis, and Suggested Best Practices 4. Future Directions and Roadmap 5. Security and Privacy - 10 Top Challenges 6. Conclusions and General Advice Appendix A. Terminology Glossary Appendix B. Solutions Glossary Appendix C. Use Case Examples Appendix D. Actors and Roles 1. Introduction and Definition The purpose of this outline is to illustrate how some initial brainstorming documents might be pulled together into an integrated deliverable. The outline will follow the diagram below. Section 1 introduces a definition of Big Data. An extended terminology Glossary is found in Appendix A. In section 2, a Reference Architecture diagram is presented followed by a taxonomy describing and extending the elements of the Reference Architecture. Section 3 maps requirements from use case building blocks to the Reference Architecture. A description of the requirement, a gap analysis, and suggested best practice is included with each mapping. In Section 4 future improvements in Big Data technology are mapped to the Reference Architecture. An initial Technology Roadmap is created on the requirements and gap analysis in Section 3 and the expected future improvements from Section 4. Section 5 is a placeholder for an extended discussion of Security and Privacy. Section 6 gives an example of some general advice. The Appendices provide Big Data terminology and solutions glossaries, Use Case Examples, and some possible Actors and Roles. Big Data Definition - “Big Data refers to the new technologies and applications introduced to handle increasing Volumes of data while enhancing data utilization capabilities such as Variety, Velocity, Variability, Veracity, and Value.” The key attribute is the large Volume of data available that forces horizontal scalability of storage and processing and has implications for all the other V-attributes. -

ZOMAYA, University of Sydney LIZHE WANG, China University of Geoscience (Wuhan) AAD VAN MOORSEL, Newcastle University RAJIV RANJAN, Chinese University of Geoscienes and Newcastle University Interest in processing big data has increased rapidly to gain insights that can transform businesses, government policies and research outcomes. This has led to advancement in communication, programming and processing technologies, including Cloud computing services and technologies such as Hadoop, Spark and Storm. This trend also affects the needs of analytical applications, which are no longer monolithic but composed of several individual analytical steps running in the form of a workflow. These Big Data Workflows are vastly different in nature from traditional workflows. Researchers arecurrently facing the challenge of how to orchestrate and manage the execution of such workflows. In this paper, we discuss in detail orchestration requirements of these workflows as well as the challenges in achieving these requirements. We alsosurvey current trends and research that supports orchestration of big data workflows and identify open research challenges to guide future developments in this area.

Several approaches have been developed in this context proposing the storage and querying of RDF data in a distributed fashion, mainly using the MapReduce Programming Model and Hadoop-based ecosystems. New trends in Big Data technologies have also emerged (e.g., Apache Spark, Apache Flink); they use distributed in-memory processing and promise to deliver higher data processing performance. In this paper, we present a formal interpretation of some PACT transformations implemented in the Apache Flink DataSet API. We use this formalization to provide a mapping to translate a SPARQL query to a Flink program. The mapping was implemented in a prototype used to determine the correctness and performance of the solution.
