MySQL Administration — Expert Reference

Use When

• Expert MySQL 8 administration: replication topology, InnoDB Cluster / Group Replication, security hardening, backup strategies with mysqldump/mydumper/xtrabackup, monitoring with Performance Schema, and production operations. Use when setting up...
• The task needs reusable judgment, domain constraints, or a proven workflow rather than ad hoc advice.

Do Not Use When

• The task is unrelated to mysql-administration or would be better handled by a more specific companion skill.
• The request only needs a trivial answer and none of this skill's constraints or references materially help.

Required Inputs

• Gather relevant project context, constraints, and the concrete problem to solve; load references only as needed.
• Confirm the desired deliverable: design, code, review, migration plan, audit, or documentation.
