When a new node joins the cluster, SST is performed to receive the data from DONOR to the JOINER. The data is internally inconsistent because the server concurrently modifies the data files while they are being copied. Percona XtraBackup performs crash recovery on the files to make a consistent, usable database again.

The main idea is to be able to easily detect what the server is doing at any point in time so we can better understand how it reacts to the workload and tune accordingly.

Without build optimizations (incremental builds, caching, we will get to those soon) this will eventually become unmanageable as well — think about going through all images in a website: resizing, deleting, and/or creating new files over and over again. Under the hood, it simplifies a lot of the work to the server-side.

Clients issue queries over data (queries can be one-off, i.e., static, or continuous).
