Re: InnoDB Cluster Distributed Recovery seemingly stuck forever

The secondary node seems to report a GTID set bigger (newer?) than the primary's which could explain why it's waiting for updates if it considers itself "ahead" of the primary. That doesn't make a lot of sense sadly, what scenario could lead a secondary node to have a more recent GTID than the primary ? I decided to disable multithreading appliers (slave_parallel_workers=1) as it wasn't enabled before we updated to 8.0.23, just in case.

mysql> SELECT @@GTID_EXECUTED;

secondary : c86adab9-8573-11eb-bd74-fa163ed5368e:1-14595759

primary : c86adab9-8573-11eb-bd74-fa163ed5368e:1-13588035
