This is a Quick Peek at what Oracle delivered with MySQL 8.0.34 and 8.1.0 on July 17th, 2023. MySQL previously released software quarterly as part of a continuous delivery system where new features were made available. Many people loved access to the new features even if they could be risky, but others wanted stability and bug fixes only.

When a new node joins the cluster, SST is performed to receive the data from DONOR to the JOINER. JOINER uses PXB to stream the data directory from DONOR. JOINER must prepare the backup before using it. It is observed that when the DONOR has a huge number of tablespaces (one million),  XtraBackup on JOINER …

When it comes to backups, there are several options for saving backup files. You can choose to save them locally on the same server, stream them to different servers, or store them in object storage. Percona XtraBackup facilitates streaming through the use of an auxiliary tool called xbcloud.

STDOUT Datasink

This diagram displays the process of streaming a backup to object storage utilizing the current STDOUT datasink:

• XtraBackup spawns multiple copy threads. Each one will be reading a chunk of data from a specific file.
