DataSource

Source: src/AWS/Bedrock/DataSource.ts

A data source attached to an Amazon Bedrock KnowledgeBase — the origin of the documents the knowledge base embeds and indexes.

The most common source is an S3 bucket. After the data source is created, start an ingestion job (bedrock-agent:StartIngestionJob) to crawl the source, chunk + embed the documents, and write them to the vector store. Ingestion is not part of the desired-state lifecycle — trigger it whenever the underlying documents change.

Creating Data Sources

import * as Bedrock from "alchemy/AWS/Bedrock";

const source = yield* Bedrock.DataSource("docs-bucket", {
  knowledgeBaseId: kb.knowledgeBaseId,
  dataSourceConfiguration: {
    type: "S3",
    s3Configuration: { bucketArn: bucket.bucketArn },
  },
  dataDeletionPolicy: "DELETE",
});
