This Snap merges the Reltio Objects (Entities or Categories) data for a given Winner and Loser entity or for category IDs as mentioned on the Tenant. It provides a potential match between the two entities.
Winner ID describes the Entity ID as a resulting 'survivor' and combines all attributes, crosswalks, roles and tags from the 'losing' entity into it.
Loser ID describes the Entity ID to be merged into the Winner (survivor) object, where an entity corresponds to one of the Reltio Objects.
ETL Transformations & Data Flow
The Snap transforms the existing entities provided as an input into a merged entity.
Input & Output
A valid Reltio account with the tenant ID for the Tenant URL, or an API key for the Account Settings to be generated.
The Reltio account must have sufficient access to merge the objects or entities from the Tenant.
|Limitations and Known Issues:|
You cannot roll back the productized Reltio Snap Pack in 4.20 to a prior version.

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.
Required. This determines the Reltio host with tenant ID. Use this format:
Default value: https://<your_reltio_host>/reltio/api/<tenant_id>
Specifies the merge operation to be performed. The available options are:
Default value: Merge Entities
Required. Specifies the Winner entity or category identifier.
This field describes the entity ID as a resulting 'survivor' and combines all the attributes, crosswalks, roles and tags from the 'losing' entity into it.
Default value: $winnerId
Required. Specifies the loser entity or the category identifier. This field describes the Entity ID to be merged in the survivor object.
Default value: $loserId
The following pipeline describes how the Snap functions as a standalone Snap in a pipeline:
The key Snap configurations for the Snap are:
The values set as the pipeline parameters:
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.
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.
