## What it is
Reshape is a zero-downtime schema migration tool for Postgres, written in Rust. It keeps old and new schemas available simultaneously via views and triggers, allowing gradual application rollouts without locking or downtime.

## Use cases
- run zero-downtime schema migrations on postgres
- rename or alter columns without locking tables
- gradually roll out database schema changes alongside app deploys
- avoid downtime from blocking DDL in production postgres
- manage complex multi-step postgres migrations automatically

## When to choose
- you run Postgres 12+ and need schema changes without downtime
- your migrations would otherwise lock tables or require manual multi-step changes
- you want old and new schemas available simultaneously during deploys

## When to avoid
- you use a database other than Postgres
- you need a simple dev-only migration runner without zero-downtime guarantees
- you rely on direct table access rather than the views Reshape creates
