批量迁移治理场景: controlled and traceable delivery
`batch-vsd-pdf` is designed for 批量迁移治理场景. The focus is consistent readability, version clarity, and rollback-ready traceability rather than one-off conversion speed. Use pilot validation, staged rollout, and anomaly logging to prevent quality drift.
Bulk migration: inventory reconciliation, failure taxonomy, reruns
- Export an inventory with relative paths, sizes, mtimes, and business owners; chunk by library and cap concurrency so duplicate submissions do not poison queues and reconciliation.
- Pilot a small slice and bucket failures: corrupt, encrypted, oversize, render anomalies; publish a fix-or-skip playbook before scaling—blind global retries waste capacity.
- Publish a reconciliation report: successes, skips, remediation backlog, and next window. Lock output names and hashes for successes; manual overrides require change control or reports and files diverge forever.
VSD to PDF (batch) FAQ
Two .vsd share a short name in different folders—will PDFs collide?
They can if outputs ignore path or content hash; key manifests by full relative path or checksum and surface collisions in the report for owners to rename or merge masters first.
Partial batch success—how do we stage acceptance?
Freeze the successful subset’s hash list per batch and notify consumers; keep failures in a separate queue—do not announce “library complete” when gaps remain.
Incremental runs: how do we catch “source changed but PDF stale”?
Compare source mtime or checksum to the last recorded value and auto-queue reconversion; filenames alone are unreliable without hashes or version fields.
Queues are long—should we raise concurrency without limits?
Model capacity first, prioritize by regulatory deadlines, and expose position/ETA—unbounded concurrency often amplifies timeouts and obscures root causes.
The migration lead leaves—how does the next person onboard?
Hand off engine versions, golden paths, reconciliation scripts, and known anomalies; tacit “we always did it this way” knowledge becomes unmaintainable within months.
