Hi All,
I’m facing a weird error. We’re migrating our old 10.1 multi-master
setup to a new 10.3 cluster (everything is running on Debian).
New-node01 is connected as a slave to the old cluster’s master.
When I tried to set up the replication between the 2 new nodes (with
data files copy), the slave thread stopped nearly immediatelly stating,
that the command is invalid – containing illegal characters. After some
investigation, it turned out, that binlog on the master (new-node01) is
– let’s say – corrupted. After a few iterations/checking I saw, that the
error always happens with some MEMORY tables (I know I can exclude them
from the replica, but want to understand the issue first)
