Apoorv Naik updated ATLAS-1780:
-------------------------------
Description:
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
