In this blog, we aim to call out some key considerations when trying to assess MySQL performance for your application. For example, if you are buying the latest Amazon memory-optimized EC2 instance (R7iz), the AWS page ( [link] ) tells us the following: Up to 3.9 For storage, FIO is generally used.

In our previous blog post we introduced Edgar, our troubleshooting tool for streaming sessions. The use of a cheaper EBS Elastic volume instead of an SSD instance store was an attractive option because AWS allows dynamic increase in EBS volume size without re-provisioning the EC2 node.

This blog article traces key developments that coincided with MongoDB’s move away from open source software, and it examines how SSPL influence might have lured others in the same direction.
