Data Model Changelog
Record changes to the ZooKeeper data model which require API version increases here.
When making a model change:
Increment the value of
MODEL_APIinmodel_api.py.Update code to use the new API by default and add backwards-compatibility handling for older versions. This makes it easier to clean up backwards-compatibility handling in the future.
Make sure code that special cases model versions either references a
model_apivariable or has a comment like MODEL_API: > {version} so that we can grep for that and clean up compatability code that is no longer needed.Add a test to
test_model_upgrade.py.Add an entry to this log so we can decide when to remove backwards-compatibility handlers.
