IPAM migration 0072 not performant with large number of existing prefixes

[jeremystretch]

Deployment Type

NetBox Cloud

NetBox Version

v4.2.2

Python Version

3.10

Steps to Reproduce

1. Create a large number of prefixes (e.g. 20,000) in a previous NetBox release.
2. Upgrade to NetBox v4.2.0 or later.

Expected Behavior

The database migrations should complete within a reasonable amount of time.

Observed Behavior

The 0072_prefix_cached_relations migration within the ipam app can take an excessively long time to complete when there exist many thousands of prefixes in the database. This is due to a missing batch_size parameter in the bulk_update() operation.

I've found a similar issue with two other v4.2 migrations affecting clusters and circuit terminations.

Glad to see this as my environment has 50K+ prefixes and 12K+ circuits w/terminations.
