Description:
Hi Team,

I was reading through MySQL documentation and stumbled upon a variable called "slave_checkpoint_period".
In the documentation for versions 5.6, 5.7 and 8.0 the variable "Unit" is specified in milliseconds, but in the  description the maximum value is specified in GBs, quote:
 "Regardless of how the server was built, the default value is 300, and the maximum possible value is 4294967296 (4GB).".

How to repeat:
Check system variable documentation in:

https://dev.mysql.com/doc/refman/5.6/en/replication-options-replica.html#sysvar_slave_chec...

https://dev.mysql.com/doc/refman/5.7/en/replication-options-replica.html#sysvar_slave_chec...

https://dev.mysql.com/doc/refman/8.0/en/replication-options-replica.html#sysvar_slave_chec...
