You’ve dumped a DB from MySQL and didn’t use the “–no-triggers” option. Now you’re trying to import your data into RDS MySQL which complains that:
ERROR 1227 (42000) at line xxx: Access denied; you need (at least one of) the SUPER privilege(s) for this operation
You can solve this by editing the dump file with ‘sed’ and then importing into RDS’s MySQL from your newly modified dump file.
sed -E 's/DEFINER=`[^`]+`@`[^`]+`/DEFINER=CURRENT_USER/g' dumpfile.sql > dumpfile_no_tags.sql
