tttjjj/elt_bench huggingface dataset:
_fivetran_synced: Timestamp of when Fivetran synced a record.
amplitude_id: An internal ID used to count unique users.
ad_id: (Android) Google Play Services advertising ID (AdID). This usually is wiped after ingestion and therefore will be blank
app: Project ID found in your project's Settings page
city: City where event was registered.
client_event_time: Local timestamp (UTC) of when the device logged the event.
client_upload_time: The local timestamp (UTC) of when the device uploaded the event.
country: Country where event was registered.
data: Dictionary where certain fields such as first_event and merged_amplitude_id are stored. Ex, {"first_event":true}
device_brand: Brand of device where event was registered on.
device_carrier: Carrier of device where event was registered on.
device_family: Device family. Ex, Apple iPhone
device_id: The device specific identifier
device_manufacturer: Manufacturer of device where event was registered on.
device_model: The model of device where event was registered on.
device_type: Type of device where event was registered on.
dma: Designated marketing area (DMA)
id: A counter that distinguishes events
event_properties: Event properties are attributes of the events your users fire, and which you then send to Amplitude. Each event will have its own set of event properties. The nature of these properties depends on both the type of product you have, and the specific information you're most interested in discovering. For instance, if Swipe is an event you're tracking, the event property Direction could have the values Left or Right. Some example event properties are description, category, type, duration, level, percent completed, count, source, status, number, lives, authenticated, error number, rank, action, and mode.
event_time: Amplitude timestamp (UTC) which is the client_event_time adjusted by the difference between server_received_time and client_upload_time, specifically: event_time = client_event_time + (server_received_time - client_upload_time) 2015-08-10T12:00:00.000000 We use this timestamp to organize events on Amplitude charts. Note: If the difference between server_received_time and client_upload_time is less than 60 seconds, the event_time will not be adjusted and will equal the client_event_time
event_type: The assigned type of event. Example 'Add Friend'
event_type_id: Internal identifier on Amplitude.
group_properties: A dictionary of key-value pairs that represent data tied to the group. Each distinct value appears as a group segment on the Amplitude dashboard. You can store property values in an array, and date values are transformed into string values.
groups: Group types. See the Accounts documentation for more information.
idfa: (iOS) Identifier for Advertiser. This usually is wiped after ingestion and therefore will be blank
ip_address: IP address
is_attribution_event: Boolean of whether event was an attribution event
language: The language set by the user
library: Library being used to send the event data.
location_lat: Latitude
location_lng: Longitude
os_name: OS name where event was registered on.
os_version: OS version where event was registered on.
paying: Boolean of whether the user has ever logged any revenue, otherwise '(none)'. Note the property value can be modified via the\_Identify API.
platform: Platform of the device.
processed_time: Time of when event was processed
project_name: Project ID
region: Region where event was registered on.
schema: Schema ID
server_received_time: Amplitude timestamp (UTC) of when servers received the event
server_upload_time: Amplitude timestamp (UTC) of when the event data was uploaded to Amplitude servers
session_id: The session start time in milliseconds since epoch
start_version: App version the user was first tracked on
user_creation_time: Event_time (UTC) of the user's first event
user_id: A readable ID specified by you
user_properties: An attribute that describes a useful detail about the user it's attached to. Amplitude sends user properties with every event.
uuid: A unique identifier per row (event sent)
version_name: The app version
