Hi Rong, thank you for your answer! I will test it with changing the pxc_strict_mode. But in your second link I can read that it would be better to add a PRIMARY_KEY to the table?

I googled this, the reason is Percona using pxc_strict_mode = ENFORCING will catch error when table without primary keys. package_to_tag table don't have a primary key. I think you can set the mode Permissive. [0] https://www.percona.com/doc/percona-xtradb-cluster/LATEST/features/pxc-stric...
