  • 1.  What Happens to Orphan Data When the Model Changes?

    Posted 24 days ago

    Suppose I remove an attribute from the data model, or remove a field from a nest. What happens to the now orphan data associated with that old attribute? 

    Does it get automatically removed?

    Hi Ronald,

    The data would still be stored in the database and will not be automatically removed.

    Ronald,

    Here is the link:


    https://docs.reltio.com/en/explore/get-going-with-apis-and-rocs-utilities/reltio-rest-apis/engage-apis/tasks-api/reindex-data-task

    Any changes to the metadata, you need to run the reindex:

    • Metadata Configuration/L3 changes such as:

      • Existing attribute changes (type, label)
      • Existing attribute is removed
      • Existed source is removed
      • Survivorship rules are modified
      • Cleanse configuration is modified
      • Lookups (RDM) mappings are modified
      • MatchFieldUris are modified
      • Surrogate crosswalks settings are modified
      • Reference attribute settings are modified
      • Sub-nested attributes are added or removed
    • Tenant's physical configuration changes in:

      • survivorshipAdvancedBehavior
      • indexOvStrategy

    One follow up question. The docs state "Note: Do not set enableSeparateIndexing to true for a subset of your data, only use it on all of your data."

    I take "subset" to mean subset within an entity type. Is that valid?

    If I have 2 entity types defined, can I safely run this on one entity type with enableSeparateIndexing = true?

    Hello User, 

    enableSeparateIndexing is at tenant level and we cannot run it for a particular entityType.

    you should definitely not do that because as Girish says, the data will still be stored and that means it will count toward your RSU.  But you don't have any way to delete it.
