Schema

Source: src/AWS/Personalize/Schema.ts

An Amazon Personalize schema — an Avro definition that describes the fields of a dataset (Interactions, Items, Users, …). Schemas are immutable once created; changing any property replaces the schema.

Creating a Schema

const schema = yield* Personalize.Schema("Interactions", {
  schema: JSON.stringify({
    type: "record",
    name: "Interactions",
    namespace: "com.amazonaws.personalize.schema",
    fields: [
      { name: "USER_ID", type: "string" },
      { name: "ITEM_ID", type: "string" },
      { name: "TIMESTAMP", type: "long" },
    ],
    version: "1.0",
  }),
});
