Migro - Юрий Богомолов

1. 2 / 8
Why?
●
Well-know db-migrate tool doesn`t support semver
– Number of fles in migrations folder grows extremely
fast.
– It`s not possible to tell which migrations correspond to
which product version.

Migro
●
Supports and endorces semver!
– It`s easy to tell which migrations where added to which
version.
●
Makes it possible to up/down migrate the DB either version
by version or by single migration.
●
Does not abstract the familiar DB client API away by its own
interface.
