Really? There are lots of tools out there which just rely on the db to run migrations.

I tried flywaydb, and some others. There are not a lot of migration tools that are not part of a bigger framework.

Can you link some examples that you think would gladly process data-migrations that are 1-2GiB large?

Anything which doesn't try to process the sql file but instead just passes it to the db to deal with, e.g.

    psql -d mydb -f migration.sql

I use a home-built solution that does this (160 lines of go), doesn't seem very exotic to me and did not require lots of work as there are only a few requirements for a working solution: Unique ordered names for migration sql files, use the db to store metadata about migrations run, use the db tools to run migrations.
