Query Store persists plan and runtime history to connect regressions with changed access paths. That principle is applicable when a query becomes slow after a new index rollout and DBAs must compare actual plan regressions across time. It does not explain the selected change in the current case, which depends on versioned reads can reduce reader-writer blocking with defined isolation semantics.

Plans and runtime views isolate query-level regressions rather than generic infrastructure symptoms. That principle is applicable when a regression begins after a stored procedure was deployed, and DBAs need exact queries causing CPU spikes. It does not explain the selected change in the current case, which depends on versioned reads can reduce reader-writer blocking with defined isolation semantics.

Deadlocks arise from cyclic lock waits; consistent ordering reduces the cycle risk. That principle is applicable when two concurrent procedures acquire customer and invoice locks in opposite orders, producing deadlock victims. It does not explain the selected change in the current case, which depends on versioned reads can reduce reader-writer blocking with defined isolation semantics.

The selected tier meets the representative workload SLO at acceptable cost. That observation would validate a different requirement: a database experiences bursts of CPU saturation and the team needs a capacity change based on measured workload rather than a blind upgrade. Here the required evidence is a long-running report sees a consistent allowed view without blocking ordinary updates.

Import and user workload both meet latency targets in the new arrangement. That observation would validate a different requirement: a transactional SQL database performs well at noon but breaches response-time SLO during nightly imports due to I/O pressure. Here the required evidence is a long-running report sees a consistent allowed view without blocking ordinary updates.

Investigators identify the slower plan and verify recovery after tuning. That observation would validate a different requirement: a query becomes slow after a new index rollout and DBAs must compare actual plan regressions across time. Here the required evidence is a long-running report sees a consistent allowed view without blocking ordinary updates.

Query Store persists plan and runtime history to connect regressions with changed access paths. Although relevant to a query becomes slow after a new index rollout and DBAs must compare actual plan regressions across time, this action would not correct the recorded production failure: rEAD UNCOMMITTED permits dirty data and does not give consistent snapshots. Use the target remedy instead.

Deadlocks arise from cyclic lock waits; consistent ordering reduces the cycle risk. Although relevant to two concurrent procedures acquire customer and invoice locks in opposite orders, producing deadlock victims, this action would not correct the recorded production failure: rEAD UNCOMMITTED permits dirty data and does not give consistent snapshots. Use the target remedy instead.

Sizing decisions should reflect observed throughput, memory, I/O and concurrency limits. Although relevant to a database experiences bursts of CPU saturation and the team needs a capacity change based on measured workload rather than a blind upgrade, this action would not correct the recorded production failure: rEAD UNCOMMITTED permits dirty data and does not give consistent snapshots. Use the target remedy instead.

Deadlocks arise from cyclic lock waits; consistent ordering reduces the cycle risk. That method solves a different requirement: two concurrent procedures acquire customer and invoice locks in opposite orders, producing deadlock victims. The current case instead requires use Query Store execution history and DMVs to correlate query text, plans and resource waits.

Concurrency control prevents lost updates or detects conflicting writes explicitly. That method solves a different requirement: two sessions update the same inventory item and the application sometimes overwrites one user's confirmed change. The current case instead requires use Query Store execution history and DMVs to correlate query text, plans and resource waits.

Tier sizing and scheduling should address observed I/O contention rather than arbitrary CPU scaling. That method solves a different requirement: a transactional SQL database performs well at noon but breaches response-time SLO during nightly imports due to I/O pressure. The current case instead requires use Query Store execution history and DMVs to correlate query text, plans and resource waits.

Concurrency control prevents lost updates or detects conflicting writes explicitly. That principle is applicable when two sessions update the same inventory item and the application sometimes overwrites one user's confirmed change.

The selected tier meets the representative workload SLO at acceptable cost. That observation would validate a different requirement: a database experiences bursts of CPU saturation and the team needs a capacity change based on measured workload rather than a blind upgrade. Here the required evidence is the team identifies the changed statement and measures reduced CPU after correction.

The second conflicting update fails or retries instead of silently overwriting a committed value. That observation would validate a different requirement: two sessions update the same inventory item and the application sometimes overwrites one user's confirmed change. Here the required evidence is the team identifies the changed statement and measures reduced CPU after correction.

A long-running report sees a consistent allowed view without blocking ordinary updates. That observation would validate a different requirement: an inventory system must allow consistent snapshot reads while concurrent writes proceed without taking broad shared read locks. Here the required evidence is the team identifies the changed statement and measures reduced CPU after correction.

Deadlocks arise from cyclic lock waits; consistent ordering reduces the cycle risk. Although relevant to two concurrent procedures acquire customer and invoice locks in opposite orders, producing deadlock victims, this action would not correct the recorded production failure: restarting the server discards useful volatile diagnostics and may hide the cause. Use the target remedy instead.

Project deployment computes target changes, but data compatibility and migration safety still require review. That method solves a different requirement: an approved database schema project contains a nullable-to-not-null change needing a safe production rollout. The current case instead requires add integration tests asserting the foreign-key relationship and expected insert failures.

Branch review exposes conflicting edits and confirms their combined behavior. That method solves a different requirement: two feature branches change the same stored procedure and one merge would silently remove another developer's fix. The current case instead requires add integration tests asserting the foreign-key relationship and expected insert failures.

Protected changes route sensitive schema and permission updates through accountable review. That method solves a different requirement: production database release must require security review for permission changes and approval from designated code owners. The current case instead requires add integration tests asserting the foreign-key relationship and expected insert failures.

Drift detection identifies differences between expected and actual database definitions. That principle is applicable when someone changed a database view directly in production and the project model no longer matches its target. It does not explain the selected change in the current case, which depends on schema integration tests catch contract changes between related database objects.

Version control records schema history, contributors and reviewed changes. That principle is applicable when a team has database definition scripts on local laptops but needs traceable reviews and restore points. It does not explain the selected change in the current case, which depends on schema integration tests catch contract changes between related database objects.

Schema changes must be data-compatible as well as syntactically valid. That principle is applicable when a release changes a populated varchar column to a narrower length and could truncate existing customer identifiers. It does not explain the selected change in the current case, which depends on schema integration tests catch contract changes between related database objects.

A fresh deployment recreates the expected status codes consistently. That observation would validate a different requirement: a production reference table contains shipping status codes that must be versioned and reproducible in each environment. Here the required evidence is cI fails when a prohibited orphan row is accepted.

The corrected project compiles without unresolved references. That observation would validate a different requirement: a build fails because a stored procedure references a renamed column in another project object. Here the required evidence is cI fails when a prohibited orphan row is accepted.

A drift report flags the index and release review makes a deliberate decision. That observation would validate a different requirement: a developer hotfixed an index directly on production, and the next declarative deployment proposes removing it. Here the required evidence is cI fails when a prohibited orphan row is accepted.

Secret-management and identity controls prevent credentials from being committed as plaintext. Although relevant to a CI deployment job currently stores an Azure SQL administrative password in repository YAML, this action would not correct the recorded production failure: a SQL syntax-only build does not test relational behavior. Use the target remedy instead.

Integration validation tests schema dependencies after resolving branch conflicts. Although relevant to database developers create parallel feature branches and a migration references an object changed by another branch, this action would not correct the recorded production failure: a SQL syntax-only build does not test relational behavior. Use the target remedy instead.

SQL Database Projects describe a target schema in source-controlled definitions. Although relevant to developers need a versioned declarative SQL schema they can build in CI without relying on a production database export, this action would not correct the recorded production failure: a SQL syntax-only build does not test relational behavior. Use the target remedy instead.
