Migration Types

Bytebase records the migration history with the migration type information.

Schema Migration

Schema migration is the migration type for DDL statements.

Data Migration

Data migration is the migration type for DML statements.

Baseline Migration

Baseline migration instructs Bytebase to use the latest live schema as the source of truth. This is normally used when schema drift occurs and Bytebase needs to re-establish the baseline based on the latest live schema.

Branch Migration

A branch migration history is recorded when a database is restored from a backup. See Restore from Backup for details.
