Design Considerations of a Blob Store

Introduction

Even though we discussed the design of the blob store system and its major components in detail in the previous lesson, a number of interesting questions still require answers. For example, how do we store large blobs? Do we store them in the same disk, in the same machine, or do we divide those blobs into chunks? How many replicas of a blob should be made to ensure reliability and availability? How do we search for and retrieve blobs quickly? These are just some of the questions that might come up.

This lesson addresses these important design concerns. The table below summarizes the goals of this lesson.
