IdNamespace

Source: src/AWS/EntityResolution/IdNamespace.ts

An AWS Entity Resolution ID namespace — a wrapper around an input dataset used by ID mapping workflows. A SOURCE namespace holds the records to be translated; a TARGET namespace holds the dataset (and the rule-based matching configuration) they are mapped onto.

Creating ID Namespaces

Source namespace over a Glue table

import * as AWS from "alchemy/AWS";

const source = yield* AWS.EntityResolution.IdNamespace("Source", {
  type: "SOURCE",
  inputSourceConfig: [
    { inputSourceARN: table.tableArn, schemaName: schema.schemaName },
  ],
  idMappingWorkflowProperties: [{ idMappingType: "RULE_BASED" }],
  roleArn: role.roleArn,
});

Target namespace with matching rules

const target = yield* AWS.EntityResolution.IdNamespace("Target", {
  type: "TARGET",
  inputSourceConfig: [
    { inputSourceARN: table.tableArn, schemaName: schema.schemaName },
  ],
  idMappingWorkflowProperties: [
    {
      idMappingType: "RULE_BASED",
      ruleBasedProperties: {
        rules: [{ ruleName: "ByEmail", matchingKeys: ["email"] }],
        ruleDefinitionTypes: ["TARGET"],
        attributeMatchingModel: "ONE_TO_ONE",
        recordMatchingModels: ["ONE_SOURCE_TO_ONE_TARGET"],
      },
    },
  ],
  roleArn: role.roleArn,
});
