Hi all,

I am reading official doc here:
https://kafka.apache.org/documentation/#messageformat, and I could not
fully understand it. If someone can clarify it for me, it would be much
appreciated. The sentence is

The partition leader epoch field is not included in the CRC computation to
avoid the need to recompute the CRC when this field is assigned for every
batch that is received by the broker.

I just don’t really get what the highlight part is trying to say.

Regards,
Xiang Zhang
