Type Alias EmbeddingProvider

An embed function supplied by the consumer on a vector index definition. Takes the text to embed and resolves to the embedding vector, which must have the dimensions declared by the index's EmbeddingModelDescriptor.

Usage example (consumer-owned Bedrock provider):

const provider: EmbeddingProvider = async text => {
  const res = await bedrock.send(
    new InvokeModelCommand({
      modelId: TitanTextEmbedV2.name,
      body: JSON.stringify({ inputText: text })
    })
  );
  return JSON.parse(new TextDecoder().decode(res.body)).embedding;
};
