Walkthrough

This change adds backend-local redo, CPU, logical-read, and physical-read statistics. It exposes the values through SYS.V$MYSTAT and names them through SYS.V$STATNAME. SQL and multi-session regression tests check view output, access grants, and session-specific counter behavior.

Merge Risk: ⚪ Minimal · up to 123ac

The grant checks and ordinary-role access tests cover the identified behavior. No issue found here prevents merging after normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 551be

The new entrypoints expose only the querying backend's counters, without granting administrative authority or allowing another session to be selected. No concrete security regression was identified. Ordinary-role direct function execution remains incompletely verified.

Retained concerns
No architecture-level concerns identified.

Security Blast Radius

• inferred — The new public access path exposes four aggregate counters and the querying backend's PID to database callers with effective schema access. Its selectable data scope is one backend process, not another session, tenant-wide statistics, or a database-wide counter store.

Trust Boundaries and Controls

• observed — The TAP source asserts that an ordinary role can read both views after SET ROLE, receives four rows bearing its backend PID, and that another connection's writes do not change the first connection's redo count. These are relevant counterevidence to cross-session disclosure; direct ordinary-role function invocation is not separately asserted.
• inferred — The isolation boundary is the backend process, not the current SQL role. Changing roles in the same connection does not create a new counter identity or reset its process-lifetime accounting.
