> Type deletion blocks ability to redefine same type with different attribute
> ---------------------------------------------------------------------------

> Key: ATLAS-1780
> URL: https://issues.apache.org/jira/browse/ATLAS-1780
> Project: Atlas
> Issue Type: Bug
> Affects Versions: 0.8-incubating
> Reporter: Apoorv Naik
> Assignee: Apoorv Naik
> Fix For: 0.9-incubating, 0.8.1-incubating
>
>
> This change supports the use-case where the user creates a type and deletes
> it sometime later, now the redefinition of the type is restricted to use the
> same data type for the attributes used during the initial creation.
> Solution: Rename the propertyKey corresponding to that attribute using the
> titan management API by suffing _deleted_xxx where xxx is an increasing
> integer sequence starting from 0. The reason for increment of xxx is that the
> type create, delete and re-create can be done multiple times without any
> conflicting key in Titan.
> Use case: Create a Tag/Trait with atleast one attribute, delete the tag,
> recreate the exact same tag with a different data type for the attribute.
> Creation will be a success, try associating the Tag/trait with any entity
> with the attribute value (new data type) this should fail with a
> ClassCastException
