Event versioning and corrections

An event is corrected later while its original occurrence time is preserved. The correction has a new processing time but the same event time, so the slot stays put while the value changes.

Detection

A later record supersedes an earlier one for the same event key.

Mitigation

Keep occurrence time fixed and version by processing time; recompute the affected slot as-of the latest version.
