In the last chapter, we implemented a sample application exposing a read-only service that provided catalog data. For the sake of simplicity, we introduced a performance bottleneck in this implementation by using file storage. This storage is not suitable for web applications. It relies on 33 physical files, preventing our application from servicing heavy loads, as file storage lacks multitenant support due to disc I/O operations. In other words, we definitely need to look for a better storage solution, which scales easily, when needed, following the demands of our REST-enabled application. NoSQL databases are now heavily used in web and in cloud environments, ensuring zero downtime and high availability. They have the following advantages over traditional transactional SQL databases:
- They support schema versions; that is, they can work with object...
