Use this practical guide to successfully handle the challenges encountered when designing an enterprise data lake and learn industry best practices to resolve issues.

When designing an enterprise data lake you often hit a roadblock when you must leave the comfort of the relational world and learn the nuances of handling non-relational data. Starting from sourcing data into the Hadoop ecosystem, you will go through stages that can bring up tough questions such as data processing, data querying, and security. Concepts such as change data capture and data streaming are covered. The book takes an end-to-end solution approach in a data lake environment that includes data security, high availability, data processing, data streaming, and more.
Each chapter includes application of a concept, code snippets, and use case demonstrations to provide you with a practical approach. You will learn the concept, scope, application, and starting point.

Practical Enterprise Data Lake Insights: Handle Data-Driven Challenges in an Enterprise Big Data Lake

Chapter 1:  Data Lake Concepts Overview
Chapter Goal: This chapter highlights key concepts of Data Lake and Tech Stack. It briefs the readers on the background of Data Management, the need to have a Data Lake, and focus on latest running trends.No of pages: 20Sub -Topics:1. Familiarization with Enterprise Data Lake ecosystem2. Understand key components of Data Lake3. Data understanding - Structured vs Unstructured
Chapter 2:  Data Replication Strategies 
Chapter Goal: The chapter will focus on how to replicate data into Hadoop from source systems. Depending on the nature of source systems, strategies may change. The chapter will start with a talk trivial approaches to ETL data into Hadoop and then dive into the latest trends of change data capture.No of pages:  25Sub - Topics: 1. Conventional ETL strategies2. Change data capture for relational data3. Change data capture for time-series data
Chapter - 3: Bring Data into Hadoop
Chapter Goal: The chapter will focus on how to get data into a Hadoop cluster. It will talk on several approaches and utilities that can be used to bring data into Hadoop for processing.Page count: 30Sub -Topics:1. RDBMS to Hadoop2. MPP database systems to Hadoop3. Unstructured data into Hadoop
Chapter 4: Data Streaming Strategies
Chapter Goal: The chapter will deep dive into data streaming principles of Kafka. It will talk on how Kafka works and understand how it resolves the challenge of getting data into Data Lake.No of pages: 50Sub - Topics:  1. How to stream the data? Kafka2. How to persist the changes3. How to batch the data4. How to massage the data5. Tools and technologies - HVR, Oracle golden gate for big data
Chapter 5: Data Processing in Hadoop
Chapter Goal: This chapter will provide an insight into various data querying platforms. It all started with Map Reduce but Hive is quickly acquiring de facto status in the industry. Chapter will deep dive into Hive, its SQL like semantics and show case its most recent capabilities. A dedicated section on Spark will give a detailed walk-through on Spark approach to process data in Hadoop.No of pages: 30Sub - Topics: 1. Map reduce2. Query engines - intro/bigdata sql/bigSQL3. Hive - focus4. Spark - focus5. Presto
Chapter 6: Data Security and Compliance
Chapter Goal: This chapter will talk on security aspects of a data lake in Hadoop. The fact that security had been deliberately compromised in the past by organizations, does has a weight. The chapter talks about how to build a safety net around data lake and mitigate the risks of unauthorized access or injection attacks on a Data Lake. Page count: 20Sub - Topics:1. Encryption in-transit and at rest2. Data masking3. Kerberos security and LDAP authentication4. Ranger 
Chapter 7: Ensure Availability of a Data Lake
Chapter Goal: This chapter throws light on yet another key aspect of data landscape i.e. availability. It will discuss topics like disaster recovery strategies, how to setup replication between two data centers, and how to tackle consistency and integrity of data.Page count: 20Sub - Topics:1. Disaster Recovery Strategies2. Setup Data center replication3. Active-passive mode4. Active-active mode
