Connecting the Data: Data Integration Techniques for Building an Operational Data Store (ODS)

By: Angelo Bobak

Overview of this book

When organizations change or enhance their internal structures, business data integration is a complex problem that they must resolve. This book describes the common hurdles you might face while working with data integration and shows you various ways to overcome these challenges. The book begins by explaining the foundational concepts of ODS. Once familiar with schema integration, you?ll learn how to reverse engineer each data source for creating a set of data dictionary reports. These reports will provide you with the metadata necessary to apply the schema integration process. As you progress through the chapters, you will learn how to write scripts for populating the source databases and spreadsheets, as well as how to use reports to create Extract, Transform, and Load (ETL) specifications. By the end of the book, you will have the knowledge necessary to design and build a small ODS.

Answer the following questions:

  1. A user changes the image of a container running in a Pod against a deployment in a Kubernetes cluster. A user updates the deployment specification. Select the option that describes the accurate behavior:

    b) A new ReplicaSet will be created with the new image running inside a new Pod and will run in parallel with the older ReplicaSet with the older image.

    c) The current running Pod will stop instantly, and a new Pod will be created with the new image. There will be some downtime.

    d) A new ReplicaSet will be created with the new image running inside a new Pod and will gradually replace Pods from the old ReplicaSet.
