The first phase involves validating functional correctness, scalability, and performance concerns and ensuring the new systems’ resilience before the migration. These include Quality-of-Experience(QoE) measurements at the customer device level, Service-Level-Agreements (SLAs), and business-level Key-Performance-Indicators(KPIs).

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.

Note: We received feedback that there was some confusion on us calling this functionality “tail of the log caching” because our documentation and prior history has referred to the tail of the log as the portion of the hardened log that has not been backed up.
