If you refer to backup, KubeBlocks provides ways to do backup with disk snapshot(supported from cloud provider like AWS EBS), file backup with tools such as xtrabackup for MySQL, wal-g for PostgreSQL. For SQL dump, a relative dump tool is recommended, such as mysql_dump for MySQL, you can dump it from the outside as a client, also, the built-in routine SQL dump will be supported in the near future. Anyway, KubeBlocks tries to integrate the best practices for any database product, the solution either provided by a well-known database provider or by an individual contributor, or by KubeBlocks official as you see from a fresh start. LoadBalancer is implemented with integrations of well-known cloud providers' LB controllers, it works in layer 4, so it can route any tcp traffics. When referring to MySQL proxy, KubeBlocks integrates vitess as proxy for apecloud-mysql(an addon in KubeBlocks, try 'kbcli addon list'), please try it out and enjoy yourself.
