CQRS lite means accepting eventual consistency on dashboards while keeping OLTP paths strict. Workers rebuild read models from changefeeds or nightly exports depending on freshness needs.

  • Define rebuild jobs that are idempotent and measurable (row counts, checksums).
  • Expose lag metrics: users should know if analytics is 30s or 30m behind.
  • Guard writes—document stores should not accept money fields without validation logic shared with SQL.

Feed the same projections into AI automation for summaries, but gate on permissioned views.
