Description:
Could you please instrument the following statistics via global status or performance schema, as they would provide visibility into binary log group commits : 
a. how many transactions were grouped into a commit and any given time , or as an average etc 
b. how many such groups have been committed so far 

As of now we do not have any way to get this information. 

How to repeat:
Perform DML on a 5.7 server and observe the statistics. 

Suggested fix:
Code the instrumentation .

Hello Bhupinder,

Thank you for the reasonable feature request!

Thanks,
Umesh
