Project Overview

A DevOps pipeline step that analyzes SQL migration scripts. Detects hazardous DDL operations that take exclusive table locks on large tables (e.g. adding columns with default values in legacy DBs) and recommends online expand-contract migration patterns.

Problem Statement

Proposed Solution
