Response Structure

  • (dict) –

    • createdAt (datetime) –

      The timestamp of when the SchemaMapping was created.

    • description (string) –

      A description of the schema.

    • hasWorkflows (boolean) –

      Specifies whether the schema mapping has been applied to a workflow.

    • mappedInputFields (list) –

      A list of MappedInputFields. Each MappedInputField corresponds to a column the source data table, and contains column name plus additional information Venice uses for matching.

      • (dict) –

        An object containing FieldName, Type, GroupName, MatchKey, and SubType.

        • fieldName (string) –

          A string containing the field name.

        • groupName (string) –

          A string that instructs Entity Resolution to combine several columns into a unified column with the identical attribute type.

          For example, when working with columns such as first_name, middle_name, and last_name, assigning them a common groupName will prompt Entity Resolution to concatenate them into a single value.

        • matchKey (string) –

          A key that allows grouping of multiple input attributes into a unified matching group. For example, consider a scenario where the source table contains various addresses, such as business_address and shipping_address. By assigning a matchKey called address to both attributes, Entity Resolution will match records across these fields to create a consolidated matching group. If no matchKey is specified for a column, it won’t be utilized for matching purposes but will still be included in the output table.

        • subType (string) –

          The subtype of the attribute, selected from a list of values.

        • type (string) –

          The type of the attribute, selected from a list of values.

    • schemaArn (string) –

      The ARN (Amazon Resource Name) that Entity Resolution generated for the SchemaMapping.

    • schemaName (string) –

      The name of the schema.

    • tags (dict) –

      The tags used to organize, track, or control access for this resource.

      • (string) –

        • (string) –

    • updatedAt (datetime) –

      The timestamp of when the SchemaMapping was last updated.
