Snap Type:Write
Description:

This Snap is used to un-merge the merged Reltio Objects (only Entities) on the mentioned Tenant. Based on Snap's configuration it is also possible to unmerge composite Entities. 

ETL Transformations & Data Flow

This

The Reltio Unmerge Snap

enables the following ETL operations/flows:

transforms the merged Reltio Objects into separate un-merged entities.

Input & Output

  • Input: 
This Snap can have an upstream Snap that can pass a document output view. Such as Structure or JSON Generator.
  • Output:
    • Prerequisites:Support and limitations:

    Modes

  • Ultra pipelines: May work in Ultra Pipelines.
    • Spark mode: Not supported in Spark mode
    • Input view is optional and is required only to pass the Origin Entity Id/ Spawn Entity Id from upstream Snaps or as a value in their corresponding properties.
    • Output: Response for the snap contains every field of each unmerged Entity.

    Modes

    Prerequisites:Reltio account with a valid Tenant Id so that Tenant URL can be formed/API for Account Settings. Also, the Reltio account must have write access in order to be able to create Objects in Tenant.
    Limitations and Known Issues

    You cannot roll back the productized Reltio Snap Pack in 4.20 to a prior version.

    Label

    Insert excerptLabelLabelnopaneltrue

     Reltio Account for information on setting up this type of account.

    Views

    InputThis Snap has exactly one document input view.
    OutputThis Snap has exactly one document output view.
    ErrorThis Snap has at most one document error view and produces zero or more documents in the view.


    Troubleshooting:None at the moment.

    Settings

    Label

    Required. The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.

    The section describes typical issues you may encounter while using this Snap, and instructions on how to workaround them:

    Settings

    Tenant URL

    Required. This determines the Reltio host with Tenant Id. The format to be used is https://<reltio_host>/reltio/api/<tenant_id>. 

    Example: https://sndbx.reltio.com/reltio/api/XK178mXYr3UZrG6/

    Default value: https://test.reltio.com/reltiotest/api/XKiqdracb178fmuXYr3U7ZrG6/


    Info

    This value can be provided dynamically as a pipeline parameter or directly in the Snap but not as an upstream parameter. 


    Operations

    This specifies the type of unmerge operation. Possible allowed values are Unmerge Entities and Not a potential match.

    • Unmerge Entities - This option performs unmerge of the provided Enitity object
    • Not a Potential Match - This option removes the “Potential Matches” option from those two entities. <need more info>

    Default value: Unmerge Entities

    Origin Entity Id

    Required. This parameter describes the composite Entity Id which is the parent Entity ID (similar to Winner Id in Reltio Merge Snap) formed during the merge operation.

    Default value: [None]


    Info

    This value can be passed either as an upstream parameter or directly in the Snap but not as a pipeline parameter. 


    Spawn Entity Id

    Required. This parameter describes the Entity Id which is the child of the merged Entity (similar to Loser Id in Reltio Merge Snap) formed during the merge operation.

    Default value: [None]


    Info

    This value can be passed either as an upstream parameter or directly in the Snap but not as a pipeline parameter. 


    Unmerge entity tree

    This option can be used for a composite Entity, an Entity that is the result of several merge operations. If enabled, every component (contributor) can be unmerged to be a standalone entity again. If not selected, only the initial state of spawn without any merges would be unmerged.

    Default value: Not selected

    Case 

    The following describes a pipeline, with a broader business logic involving multiple ETL transformations, that shows how typically in an enterprise environment, the Reltio functionality is used. The pipeline download is available in the Downloads section.

    This pipeline retrieves the data from the Oracle Database and loads into the Reltio instance.

    Image Added


    The key ETL transformations: 

    Extract: The Oracle Select Snap retrieves the data from Oracle database.

    Transform: The Head and the Mapper Snaps maps the specific data to be moved into the Reltio instance.

    Load: The Reltio Create Snap creates the entities from the documents received from the upstream.

    The pipeline further uses the Reltio Merge, Unmerge  and the Delete Snaps to perform the respective functions while transforming ( the JSON Splitter, Mapper and the Head Snaps) the data to serve the various business purposes.
