Known risks and operator-recorded values for Rackspace schema snapshots
Step 0 reports exist only in the operator-selected local directory. The application, Blob, and Git do not contain a copy. If the operator loses a report, Step 0 evidence must be collected again.
AUTO_INCREMENT counters and other returned metadata can change often. A refresh can produce a
pull request without a structural schema change.
MySQL couples some metadata statements to broader privileges. The snapshot account can read rows
through views because SHOW CREATE VIEW requires SELECT on the view. The TRIGGER and EVENT
grants also permit trigger and event changes. MySQL grants cannot remove these couplings. The
account password, TLS, firewall allowlist, and reviewed grant list limit this exposure.
Exact DEFINER clauses expose MySQL account names. Git history keeps those values after a later
file change.
Drizzle Kit can omit or transform MySQL features that it does not model. The exact DDL snapshot is the fallback record, not proof that generated TypeScript supports every object.
A valid Drizzle Kit pull can contain TypeScript that conflicts with repository compiler settings.
Every registry update must pass the @concourse/rsdb type check before merge.
A failed refresh keeps the last merged schema available to applications. Rackspace can change while that schema is stale. The run report and pull request must identify each stale database.
The installed Rackspace MySQL version can return different metadata columns or syntax. Discovery must use the live version as the compatibility target.
Dozens of full baselines can add significant Git history. The first implementation must record artifact sizes and Git API use during the staged rollout.
Dozens of generated schema modules can increase TypeScript work and deployment bundle size. The staged rollout must record type-check time, build time, and the deployed application bundle size.
One runtime process can select many databases and create many cached pools. The implementation must use conservative pool limits and close idle factory instances at their lifecycle boundary.
The runtime account can change application rows. An application defect or exposed credential can damage Rackspace data. The account must not have schema or grant-management privileges.
A zero-row query verifies connectivity and generated identifiers. It does not verify row decoding, application business queries, stored routine behavior, triggers, or real data quality. Application features still need tests for the queries that they own.
An all-database check can issue many metadata and zero-row queries. Sequential execution, timeouts, and the single-workflow lock limit concurrent Rackspace load. The run report must include query counts and durations.
Sequential processing protects Rackspace but increases total elapsed time. Durable workflow state must permit the refresh to continue after a function restart.
Privilege changes can remove a database from inventory. The workflow keeps the existing snapshot until a reviewer approves removal.
The exact Rackspace MySQL version and TLS configuration are not deferred decisions. An operator must record them before implementation starts. The version selects the grant table, the routine discovery method, and the Drizzle Kit compatibility target.
Step 0 must record these operator values:
