VectorsRead

Source: src/AWS/S3Vectors/VectorsRead.ts

Read-only runtime binding for the S3 Vectors data plane — query, get, and list vectors in a bound Index.

Grants only s3vectors:QueryVectors, s3vectors:GetVectors, and s3vectors:ListVectors on exactly the bound index’s ARN — the least-privilege choice for retrieval-only consumers (e.g. a RAG search endpoint that never writes embeddings). Provide the implementation with Effect.provide(AWS.S3Vectors.VectorsReadHttp).

Reading Vectors

// init
const vectors = yield* AWS.S3Vectors.VectorsRead(index);

// runtime
const result = yield* vectors.query({
  topK: 5,
  queryVector: { float32: [0.1, 0.2, 0.3] },
  returnDistance: true,
});
