NucliaDB Migrations
This module is used to manage NucliaDB Migrations.
All migrations will be provided in the migrations
folder and have a filename
that follows the structure: [sequence]_[migration name].py
.
Where sequence
is the order the migration should be run in with zero padding.
Example: 0001_migrate_data.py
.
Each migration should have the following:
from nucliadb.migrator.context import ExecutionContext
async def migrate(context: ExecutionContext) -> None:
"""
Non-kb type of migration. Migrate global data.
"""
async def migrate_kb(context: ExecutionContext, kbid: str) -> None:
"""
Migrate kb.
Must have both types of migrations.
"""
How migrations are managed
-
All migrations utilize a distributed lock to prevent simulateously running jobs
-
Global migration state:
- current version
- target version
- KBs to migrate
-
KB Migration State:
- current version
-
Migrations are currently run with a deployment and will be continuously retried on failure.
-
Running migrations in a deployment is to make sure a migration does not prevent code deployment.
