Hi all!The Cognite Data Modelling product team are looking to make an improvement to how properties from views selected in data modelling graph queries are included in the result data set.The documented and desired behaviour is that only view properties that are explicitly selected in the query will be included in the data output. However, there is a known issue with property selection where in some cases a query would return more properties per view than initially selected.The issue manifests such that properties selected on one view will also be included in the result properties of another view in the query. This behaviour only appears in specific cases: the selection should be in the same table expression, the selection should use two or more views that share some container properties, and one or more shared properties (that is, properties mapped to the same container property) should be selected in one of the views but not in the other.As such, the issue does not cause a data leak
Hi all!This is an update from the Data Modeling team on an upcoming change.We are making a change in how we treat the absence of data in an object when making a query in a data model graph. Currently, if an instance has no value in an optional property, it will not be included in the response to a query for instances where that property is NOT some value.As an example, consider a field “completionYear” which is not always populated - a query for instances where completionYear is NOT “2023” would return only instances where completionYear has a value, and that value is not 2023. Instances where that property is not set would not be included.We intend to change this behavior such that instances without a value in that property would be included in the query reseponse, as this behavior is more in line with the expected behavior in most cases. This also resolves an inconsistency with the search and aggregation queries where this behavior is already happening.We consider this a bug fix, so
