Hi! I’ve noticed unexpected behavior when relying on GTID as a replication pointer.

Assume MySQL has executed the following transactions:

b1988e6b-e20e-11ee-916d-0242ac350008:1 b1988e6b-e20e-11ee-916d-0242ac350008:2 b1988e6b-e20e-11ee-916d-0242ac350008:3 b1988e6b-e20e-11ee-916d-0242ac350008:4 ... b1988e6b-e20e-11ee-916d-0242ac350008:300 

Upon connection, the script informs the master node that the latest processed transaction is: b1988e6b-e20e-11ee-916d-0242ac350008:300. However, for some reason, MySQL continues to send past transactions (1,2,3,4 ... ), leading to event data duplication.

What could be causing this issue?
