slight off topic - but for which this one is used for - “adobe_target_classification_events” dataset?

I thought about offline sources. Additionally I found Google Pubsub

I know:- streaming API- kafka - azure events - Amazon Kinsesis Is it anything else?

Have you implemented using one tag multiple websites which use different technologia - SPA and MPA? What should I look at or be careful with?

in a batch way for futher analytics

My customer has AEM on cloud + ATIs it possible to use with Experience Fragment Replace functionality? Was it removed? 

So I can have 3 domains with 100 email channel configurations? I thought that I can manage marketing consents based on mapping Marketing Actions with channel configurations  

Whats the limit? I do not see that in AJO guardrails

I thought about external Data Mart

I see these options:1. There are connectors like SFTP / BigQuery2. Is there any API which can send data futher? Which API?3. Maybe external tool can access specific profile dataset and get these data? Which API?
