I am using Mongodb on some flavor of Linux on a work sever. There are many web services that offer mongoDB hosting, including MongoDB Atlas which gives you free mongoDB databases. The New York Times uses MongoDB in form building applications. HSE is a fast embeddable key-value store designed for SSDs and persistent memory. A NoSQL (originally referring to "non-SQL" or "non-relational") database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases.Such databases have existed since the late 1960s, but the name "NoSQL" was only coined in the early 21st century, triggered by the needs of Web 2.0 companies. “Persistent Volume Claims” and three volumes . mongodb-persistent uses a persistent volume store for the database data which means the data will survive a pod restart. The storage portion is important (and confusing) enough to warrant special attention. If yes then what should be the path? When deploying database applications like MongoDB in a Docker Container solution, persistent storage becomes a mandatory requirement.

Enforcing quotas in this way allows the developer to request persistent storage by a specific amount (for example, 10Gi) and be matched with a corresponding volume of equal or greater capacity. Persistent storage lets you do more with your Shiny apps. Even if the amount of data is very small (with a capacity of more than 1g), it takes up more than 1g of memory when running.
