create_matching_workflow#

EntityResolution.Client.create_matching_workflow(**kwargs)#

Creates a MatchingWorkflow object which stores the configuration of the data processing job to be run. It is important to note that there should not be a pre-existing MatchingWorkflow with the same name. To modify an existing workflow, utilize the UpdateMatchingWorkflow API.

Parameters:

  • description (string) – A description of the workflow.

  • incrementalRunConfig (dict) –

    An object which defines an incremental run type and has only incrementalRunType as a field.

    • incrementalRunType (string) –

      The type of incremental run. It takes only one value: IMMEDIATE.

  • inputSourceConfig (list) –

    [REQUIRED]

    A list of InputSource objects, which have the fields InputSourceARN and SchemaName.

    • (dict) –

      An object containing InputSourceARN, SchemaName, and ApplyNormalization.

      • applyNormalization (boolean) –

        Normalizes the attributes defined in the schema in the input data. For example, if an attribute has an AttributeType of PHONE_NUMBER, and the data in the input table is in a format of 1234567890, Entity Resolution will normalize this field in the output to (123)-456-7890.

      • inputSourceARN (string) – [REQUIRED]

        An Glue table ARN for the input source table.

      • schemaName (string) – [REQUIRED]

        The name of the schema to be retrieved.

    [REQUIRED]

    A list of OutputSource objects, each of which contains fields OutputS3Path, ApplyNormalization, and Output.

    • (dict) –

      A list of OutputAttribute objects, each of which have the fields Name and Hashed. Each of these objects selects a column to be included in the output table, and whether the values of the column should be hashed.

      • KMSArn (string) –

        Customer KMS ARN for encryption at rest. If not provided, system will use an Entity Resolution managed KMS key.

      • applyNormalization (boolean) –

        Normalizes the attributes defined in the schema in the input data. For example, if an attribute has an AttributeType of PHONE_NUMBER, and the data in the input table is in a format of 1234567890, Entity Resolution will normalize this field in the output to (123)-456-7890.

      • output (list) – [REQUIRED]

        A list of OutputAttribute objects, each of which have the fields Name and Hashed. Each of these objects selects a column to be included in the output table, and whether the values of the column should be hashed.

        • (dict) –

          A list of OutputAttribute objects, each of which have the fields Name and Hashed. Each of these objects selects a column to be included in the output table, and whether the values of the column should be hashed.

          • hashed (boolean) –

            Enables the ability to hash the column values in the output.

          • name (string) – [REQUIRED]

            A name of a column to be written to the output. This must be an InputField name in the schema mapping.

      • outputS3Path (string) – [REQUIRED]

      An object which defines the list of matching rules to run and has a field Rules, which is a list of rule objects.

      • attributeMatchingModel (string) – [REQUIRED]

        The comparison type. You can either choose ONE_TO_ONE or MANY_TO_MANY as the AttributeMatchingModel. When choosing MANY_TO_MANY, the system can match attributes across the sub-types of an attribute type. For example, if the value of the Email field of Profile A and the value of BusinessEmail field of Profile B matches, the two profiles are matched on the Email type. When choosing ONE_TO_ONE ,the system can only match if the sub-types are exact matches. For example, only when the value of the Email field of Profile A and the value of the Email field of Profile B matches, the two profiles are matched on the Email type.

          An object containing RuleName, and MatchingKeys.

          • matchingKeys (list) – [REQUIRED]

            • (string) –

          • ruleName (string) – [REQUIRED]

            A name for the matching rule.

  • roleArn (string) –

    [REQUIRED]

    The Amazon Resource Name (ARN) of the IAM role. Entity Resolution assumes this role to create resources on your behalf as part of workflow execution.

  • tags (dict) –

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

    • (string) –

      • (string) –

  • workflowName (string) –

    [REQUIRED]

    The name of the workflow. There cannot be multiple DataIntegrationWorkflows with the same name.

Return type:
