class Aws::PersonalizeEvents::Types::Event

Represents user interaction event information sent using the `PutEvents` API.

@note When making an API call, you may pass Event

data as a hash:

    {
      event_id: "StringType",
      event_type: "StringType", # required
      event_value: 1.0,
      item_id: "ItemId",
      properties: "EventPropertiesJSON",
      sent_at: Time.now, # required
      recommendation_id: "RecommendationId",
      impression: ["ItemId"],
    }

@!attribute [rw] event_id

An ID associated with the event. If an event ID is not provided,
Amazon Personalize generates a unique ID for the event. An event ID
is not used as an input to the model. Amazon Personalize uses the
event ID to distinquish unique events. Any subsequent events after
the first with the same event ID are not used in model training.
@return [String]

@!attribute [rw] event_type

The type of event, such as click or download. This property
corresponds to the `EVENT_TYPE` field of your Interactions schema
and depends on the types of events you are tracking.
@return [String]

@!attribute [rw] event_value

The event value that corresponds to the `EVENT_VALUE` field of the
Interactions schema.
@return [Float]

@!attribute [rw] item_id

The item ID key that corresponds to the `ITEM_ID` field of the
Interactions schema.
@return [String]

@!attribute [rw] properties

A string map of event-specific data that you might choose to record.
For example, if a user rates a movie on your site, other than movie
ID (`itemId`) and rating (`eventValue`) , you might also send the
number of movie ratings made by the user.

Each item in the map consists of a key-value pair. For example,

`\{"numberOfRatings": "12"\}`

The keys use camel case names that match the fields in the
Interactions schema. In the above example, the `numberOfRatings`
would match the 'NUMBER\_OF\_RATINGS' field defined in the
Interactions schema.
@return [String]

@!attribute [rw] sent_at

The timestamp (in Unix time) on the client side when the event
occurred.
@return [Time]

@!attribute [rw] recommendation_id

The ID of the recommendation.
@return [String]

@!attribute [rw] impression

A list of item IDs that represents the sequence of items you have
shown the user. For example, `["itemId1", "itemId2", "itemId3"]`.
@return [Array<String>]
