The short answer is yes. In any case, flink wil spend time/cpu to invoke the timer.

I want to store the number of customers in the state and also I am registering onTimer for all the customer_ids. I wanted to understand if we register something around 70 Million Keys and we have onTimer registered for those keys. Will there be any overhead and if yes what will be the overhead, will it impact processing time? Thanks and Regards , Surendra Lalwani IMPORTANT NOTICE: This e-mail, including any attachments, may contain confidential information and is intended only for the addressee(s) named above.
