MySQL 8 has made some great improvements on the replication side. MySQL 8 is all about scalability, performance, and security with the utmost integrity of data, which is expected to be a game-changer in big data too.

This results in a better throughput if the overall number of writes doesn't exceeding the capacity of the members in group replication. If there is a case where capacity is not planned appropriately, you would notice lags on affected members as compared to other members in the group.
Infrastructure sizing
