4. Operational tips

4.1. Field notes

  • Common pitfalls and fixes from production deployments

  • Runbook snippets and troubleshooting checklists

  • Telemetry queries for quick health assessments

4.2. Highlights

  • Multi‑class patterns: either UNION class tables or build an index via spMFObjectTypeUpdateClassIndex.

  • Resetting class tables after metadata changes: drop and recreate, or refresh with spMFDropAndUpdateMetadata before updates.

  • Adding ad‑hoc properties: ensure they exist in MFProperty, add columns in class table (including _id for lookups), and register in MFClassProperty.

  • Auditing updates: MFUpdateHistory with spMFUpdateHistoryShow to list affected records.

  • Detecting deletions: run spMFTableAudit when using MFLastModified bounded updates.
