14.11 Version Control

TDengine IDMP has a built-in Git-based version control system that persists all asset model metadata (elements, templates, dashboards, panels, analyses, connections, libraries, etc.) as JSON files in a Git repository, enabling users to track, review, and roll back every change.

Why Version Control?​

In industrial scenarios (such as pharmaceuticals and energy), changes to asset models require strict process control:

  • Change Traceability: Who changed what attribute, when, and why?
  • Approval Workflow: Critical changes must be reviewed before taking effect.
  • Rollback Capability: Quickly restore to any historical version after misoperation.
  • Compliance Requirements: Meet FDA 21 CFR Part 11, EU Annex 11, and other regulatory requirements.

IDMP chose Git as its version control engine because it natively provides complete history, diff comparison, branch management, and merge capabilities — the industry's most mature version control solution.
