Database Internals

Use When

• Deep database internals: B-tree storage, WAL/REDO logging, MVCC, buffer pool mechanics, transaction isolation, and distributed database concepts. Use when making database design decisions that require understanding how MySQL works internally —...
• 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 database-internals 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.
