SchemaMapping

Source: src/AWS/EntityResolution/SchemaMapping.ts

An AWS Entity Resolution schema mapping — the schema of an input customer records table. It tells Entity Resolution the attribute type of each column (name, email, phone, unique id, …) and which columns rule-based matching compares via matchKey.

Creating Schema Mappings

import * as AWS from "alchemy/AWS";

const schema = yield* AWS.EntityResolution.SchemaMapping("Customers", {
  mappedInputFields: [
    { fieldName: "id", type: "UNIQUE_ID" },
    { fieldName: "email", type: "EMAIL_ADDRESS", matchKey: "email" },
    { fieldName: "name", type: "NAME", matchKey: "name" },
  ],
});

Matching Workflows

const workflow = yield* AWS.EntityResolution.MatchingWorkflow("Dedupe", {
  inputSourceConfig: [
    { inputSourceARN: table.tableArn, schemaName: schema.schemaName },
  ],
  // ...
});
