FCM Analytics

[Visarn Patton]

I was reading on adding analytics label from https://firebase.google.com/docs/cloud-messaging/understand-delivery?platform=android

From the documentation, it stated that 

Analytics labels are text strings in the format ^[a-zA-Z0-9-_.~%]{1,50}$. Labels can include lower and upper case letters, numbers, and the following symbols:

• -
• ~
• %

Max length is 50 characters. You can specify up to 100 unique labels per day; messages with labels added beyond that limit are not reported.

I was wondering if this is a limitation on FCM console only ? because my firebase project is setup to export to bigquery

From the data from Google Analytcs, I see that the label length can go beyond 50 characters and I see that there are more than 100 unique label in bigquery

Appreciate anyone who has nowledge in this area

Thank you

The published limits are what we officially support.

Are you sending more than 100 unique labels in a single day? Do all of your labels display? Do they display at full length?

[Visarn Patton]

Yes, I have tried sending more than 100  unique labels and I can see it in Bigquery.

And they display at full length which at times more than 50 characters

Glad to hear that works for you! That said, there is no guarantee this behaviour will persist but also no imminent changes to the system that would change it.

Proceed at your own discretion.
