MongoDB Memory Management Demystified

Technical topics covered: Capacity Planning, Monitoring, Schema Design | Languages used: Python | Size of Deployment: 3 shard cluster (growing to 50)

Understanding how memory is managed with MongoDB is instrumental in maximizing database performance and hardware utilisation. This talk covers the workings of low level operating system components like the page cache and memory mapped files. We will examine the differences between RAM, SSD and hard disk drives to help you choose the right hardware configuration. Finally, we will learn how to monitor and analyze memory and disk usage using the MongoDB Management Service, linux administration commands and MongoDB commands.
