Data-only

When to use it

• target tables already exist
• you only need to backfill or refresh data
• schema creation is handled separately

migration.toml

schema = "app"
data_only = true
workers = 8

[source]
type = "mysql"
dsn = "root:root@tcp(127.0.0.1:3306)/source_db"

[target]
dsn = "postgres://postgres:postgres@127.0.0.1:5432/target_db?sslmode=disable"
