Introduction to the Is Replica Of Check

Deprecated: use Data Diff instead

The Is Replica Of rule is no longer maintained. Data Diff replaces it with the same row-by-row comparison plus change-type filtering. This page is kept as a reference for checks that already exist; new checks should use Data Diff.

The Is Replica Of check compares a target container against a reference container row by row and reports that the two do not match. This rule is deprecated: Data Diff replaces it and should be used for every new check.

This section is the complete guide to the check. The Deep Dive covers the definition, properties, and full evaluation semantics, explains how anomalies are reported, walks through production examples, and collects best practices; the How-tos are step-by-step tutorials for creating, editing, and deleting a check; the API page documents the payload for programmatic use; and the FAQ answers the most frequent questions.
