Hello !
I would like to measure MAU/DAU with S3 Exported data format.
Define MAU such that
MAU(/DAU) : Monthly(/Daily) Unique Active Event WHERE user_id != None
And here is the exported data JSON object schema:
{
"server_received_time": UTC ISO-8601 timestamp,
"app": int,
"device_carrier": string,
"$schema":int,
"city": string,
"user_id": string,
"uuid": UUID,
"event_time": UTC ISO-8601 timestamp,
"platform": string,
"os_version": string,
"amplitude_id": long,
"processed_time": UTC ISO-8601 timestamp,
"user_creation_time": UTC ISO-8601 timestamp,
"version_name": string,
"ip_address": string,
"paying": boolean,
"dma": string,
"group_properties": dict,
"user_properties": dict,
"client_upload_time": UTC ISO-8601 timestamp,
"$insert_id": string,
"event_type": string,
"library":string,
"amplitude_attribution_ids": string,
"device_type": string,
"device_manufacturer": string,
"start_version": string,
"location_lng": float,
"server_upload_time": UTC ISO-8601 timestamp,
"event_id": int,
"location_lat": float,
"os_name": string,
"amplitude_event_type": string,
"device_brand": string,
"groups": dict,
"event_properties": dict,
"data": dict,
"device_id": string,
"language": string,
"device_model": string,
"country": string,
"region": string,
"is_attribution_event": bool,
"adid": string,
"session_id": long,
"device_family": string,
"sample_rate": null,
"idfa": string,
"client_event_time": UTC ISO-8601 timestamp,
}
Can you help me figure out which column to refer to in order to calculate MAU metric?
Also if there are any specification for this JSON object schema, please let me know.
Just to let you know, I have tried following queries but all of these gave an output which differed from what amplitude application showed.
- SELECT(DISTINCT uuid) FROM table WHERE user_id IS NOT NULL
- SELECT(DISTINCT user_id) FROM table WHERE user_id IS NOT NULL
- SELECT(DISTINCT event_id) FROM table WHERE user_id IS NOT NULL
- etc.
Thank you !
