Dataset

Source: src/AWS/Forecast/Dataset.ts

An Amazon Forecast dataset — a typed, domain-scoped collection of time-series (or metadata) records described by a schema. Creating the dataset is a cheap metadata operation; bulk imports and training happen through separate import jobs and predictors.

Creating a Dataset

const dataset = yield* Forecast.Dataset("Demand", {
  domain: "CUSTOM",
  datasetType: "TARGET_TIME_SERIES",
  dataFrequency: "D",
  schema: {
    attributes: [
      { attributeName: "item_id", attributeType: "string" },
      { attributeName: "timestamp", attributeType: "timestamp" },
      { attributeName: "target_value", attributeType: "float" },
    ],
  },
});
