MySQL 8.0 Release Notes
MySQL 8.0 Source Code Documentation
From MySQL 8.0.26, checkpoints and advancing the checkpoint LSN
are not permitted until redo log recovery is complete and data
dictionary dynamic metadata (srv_dict_metadata)
is transferred to data dictionary table
(dict_table_t) objects. Should the redo log run
out of space during recovery or after recovery (but before data
dictionary dynamic metadata is transferred to data dictionary
table objects) as a result of this change, an
innodb_force_recovery restart may
be required, starting with at least the
SRV_FORCE_NO_IBUF_MERGE setting or, in case
that fails, the SRV_FORCE_NO_LOG_REDO setting.
If an innodb_force_recovery
restart fails in this scenario, recovery from backup may be
necessary. (Bug #32200595)
