Design Considerations in a Blob Store

Introduction

Even though we discussed the design and its major components in detail in the previous lesson, a number of interesting questions need answering. For example, how do we store (large) blobs? In the same disk, in the same machine or divide it into chunks? How many replicas of a blob should be made to ensure reliability and availability? How to search and retrieve blobs quickly, etc.

This lesson answers such important design concerns. The table below summarizes the goals of this lesson.
