Data Lake Development with Big Data

By: Pradeep Pasupuleti, Beulah Salome Purra

Overview of this book

A Data Lake is a highly scalable platform for storing huge volumes of multistructured data from disparate sources with centralized data management services. This book explores the potential of Data Lakes and explores architectural approaches to building data lakes that ingest, index, manage, and analyze massive amounts of data using batch and real-time processing frameworks. It guides you on how to go about building a Data Lake that is managed by Hadoop and accessed as required by other Big Data applications. This book will guide readers (using best practices) in developing Data Lake's capabilities. It will focus on architect data governance, security, data quality, data lineage tracking, metadata management, and semantic data tagging. By the end of this book, you will have a good understanding of building a Data Lake for Big Data.

Chapter 4. Data Discovery and Consumption

In the previous chapters, we discussed the Data Intake and Data Management tiers. During intake, we have seen that the data is ingested from disparate sources and stored in the Raw Zone. The Data Management Tier performs data profiling and validation; integrates, cleanses, standardizes, and enriches the data and places it in the Data Hub Zone.

Let us now understand how this data can be discovered, packaged, and provisioned for it to be consumed by the downstream systems. Data Consumption comprises Data Discovery and Data Provisioning. In this chapter, we will enable you to understand the following topics:

  • The process of enabling discovery in the Data Lake

  • The various Data Discovery functionalities

  • The important aspects of Data Provisioning such as data publication and subscription.

  • The architectural guidance on choosing Big Data tools and technologies for Data Discovery and Data Provisioning
