Vectors

Source: src/AWS/S3Vectors/Vectors.ts

Read-write runtime binding for the S3 Vectors data plane — read and write vectors in a bound Index.

Bind an Index inside a function runtime to get a VectorsClient with put / query / get / list / delete. The binding grants read+write s3vectors:*Vectors actions scoped to exactly the bound index’s ARN. This is the natural read/write pairing for a vector store — the key enabler for building embedding search and RAG retrieval on top of S3 Vectors. For least privilege, prefer VectorsRead (query/get/list) or VectorsWrite (put/delete) where one direction suffices.

Reading and Writing Vectors

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

// runtime — insert
yield* vectors.put({
  vectors: [
    { key: "doc-1", data: { float32: [0.1, 0.2, 0.3] } },
  ],
});

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