Hi, I am relatively new to dgraph and after going through all the tutorials I’m still a bit confused on whats the best practice for data migration on the database.
I’m not talking about migrating from e.g. mongo/postgress/mysql to dgraph but more so about adding/deleting/renaming predicates or adjusting indexes. I would like to be able to keep track of these migrations I have run and be able to revert if needed. Also when running a migration does this prevent the user from performing reads/writes. If so then I can just do migrations during maintenance hours.
