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.

[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 Amazon Resource Name (ARN) for the input source table.
  - schemaName (string) – [REQUIRED]
    
    The name of the schema to be retrieved.
outputSourceConfig (list) –
[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.

        Enables the ability to hash the column values in the output.
      - name (string) – [REQUIRED]

    The comparison type. You can either choose ONE_TO_ONE or MANY_TO_MANY as the attributeMatchingModel.
    
    If you choose 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 attribute type.
    
    If you choose ONE_TO_ONE, the system can only match attributes if the sub-types are an exact match. For example, for the Email attribute type, the system will only consider it a match if the value of the Email field of Profile A matches the value of the Email field of Profile B.
  - matchPurpose (string) –
    
    An indicator of whether to generate IDs and index the data or not.
    
    If you choose IDENTIFIER_GENERATION, the process generates IDs and indexes the data.
    
    If you choose INDEXING, the process indexes the data without generating IDs.
  - rules (list) – [REQUIRED]
    
    A list of Rule objects, each of which have fields RuleName and MatchingKeys.
    - (dict) –
      
      An object containing RuleName, and MatchingKeys.
      - matchingKeys (list) – [REQUIRED]
        
        A list of MatchingKeys. The MatchingKeys must have been defined in the SchemaMapping. Two records are considered to match according to this rule if all of the MatchingKeys match.
        
        (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]
