cutover

Public version of Cutover MCP

A typed Python work-order service for short-TTL DNS cutover and rollback.

A reproducible CDC cutover and replay project for validating event ordering, recovery behavior, and consistent state transitions during database change-data-capture migrations.

Live on-prem MySQL to Aurora migration with AWS DMS: full load + CDC while orders kept arriving, row-by-row validation, a gated cutover with automatic rollback (284.8 s measured downtime), two trap drills (binlog off, premature cutover), and a MySQL to PostgreSQL comparison of what DMS does not carry across.

Open-source playbook generator for ERP and infrastructure cutovers — go/no-go checkpoints, dependency mapping, rollback triggers

Check DNS propagation of a record across 18 public resolvers worldwide — parallel queries, consensus detection, watch mode, and CI-friendly exit codes. Python CLI, zero config.

Typed Python workflow for a short-TTL payment hostname cutover and rollback

Reconciles primary keys and compares column aggregates between the legacy table and the new warehouse, so a cutover that reports success while short 42 orders gets blocked instead of signed off.

Typed Python service for short-TTL developer-tools DNS releases and rollback diagnostics.

Model cutover dependencies, execution waves, blockers, critical paths, controls, and evidence as a versionable graph.

Evidence-gated Python service for a short-TTL logistics DNS cutover with an explicit rollback value.

Coordinate Vitess Online DDL across every shard of a keyspace. Submits with --postpone-completion, holds a global cutover barrier until all shards report ready and none is lagging, then completes them together — turning per-shard schema skew into zero. Live progress, throttle guard, revert, resumable journal, and a deterministic cluster simulator.

Python service for staged creator storefront CNAME changes and rollback.

Executable MarTech migration assurance system for semantic reconciliation, safe cutover, crash recovery, and reversible customer-platform replacement.
