New Features and Enhancements

Section titled “New Features and Enhancements”
  • When you deploy a model to Snowflake, a standalone property now deploys as its own table instead of a column on the concept’s table. A standalone property is one you write as brand = model.Property(...) rather than attaching it to a concept with Car.brand = model.Property(...). If your deployed model has downstream consumers, you will need to update any that expect properties as columns.

Bug Fixes

Section titled “Bug Fixes”

  • Deploying a model no longer overwrites or deletes another model’s objects when both models deploy into the same Snowflake schema with the same deployment.managed_tag.

  • Some models that previously failed to deploy to Snowflake with SQL compilation error: Unsupported subquery type cannot be evaluated now deploy successfully.

  • When you deploy a model to Snowflake, the geometric_mean aggregate over data that can include negative numbers no longer fails and now returns NaN for those cases.

  • An aggregate grouped per entity with .per() in a model deployed to Snowflake now returns each entity’s own value instead of a whole-table total or a count that is too high. A few cases that cannot be computed correctly now raise a clear LookupBoundAfterAggregate error instead of a silent wrong number.

  • Calling as_bool() on a where clause with several conditions now returns one True or False per row instead of duplicated rows or missing False rows.

  • Improved performance for deploying a model to Snowflake when it contains a concept whose properties are built up across many definitions.

  • If you deploy a model from a Snowflake notebook using get_active_session(), it no longer fails with a false Deploy lease ... was taken over by another deploy error.

  • After a branch creation fails, you can now tear down the incomplete branch with the rai models teardown --force command and retry.

  • If a Problem reads another Problem’s results before that Problem has been solved, solving or deploying it now raises a clear error instead of returning a misleading OPTIMAL result. Solve or configure the Problem it reads from first.

  • If you query a model inside a Snowflake stored procedure, it no longer fails at startup with ImportError: cannot import name '_ExtendedAttributes'.
