Index

Source: src/AWS/Kendra/SearchIndex.ts

An Amazon Kendra index — a machine-learning powered enterprise search index that data sources (S3, SharePoint, databases, …) sync documents into and that applications query with natural language.

Caution

Provisioning an index takes ~20–30 minutes and bills hourly from the moment the index becomes ACTIVE (including the Developer edition’s free-tier-exhausted rate). Destroy indexes promptly.

Creating Indexes

import * as AWS from "alchemy/AWS";

const role = yield* AWS.IAM.Role("KendraRole", {
  assumeRolePolicy: {
    Version: "2012-10-17",
    Statement: [{
      Effect: "Allow",
      Principal: { Service: "kendra.amazonaws.com" },
      Action: "sts:AssumeRole",
    }],
  },
  policies: [{
    policyName: "logs",
    policyDocument: {
      Version: "2012-10-17",
      Statement: [{
        Effect: "Allow",
        Action: ["logs:*", "cloudwatch:PutMetricData"],
        Resource: "*",
      }],
    },
  }],
});

const index = yield* AWS.Kendra.Index("Search", {
  edition: "DEVELOPER_EDITION",
  roleArn: role.roleArn,
});
