AWS RDS MySQL 5.6.x issue:
Created a MySQL database on the AWS RDS platform. Created a dozen tables, imported data to all tables and can SELECT from all tables.
Granted all privileges to user on database schema.
grant all privileges on mysqldb.* to 'username'@'%';
However, cannot create indexes or change collation. The following commands just hang and never return:
alter schema mysqldb default character set utf8 default collate utf8_general_ci; create index ix_mytable on mytable(mycol);
And there are no error messages reported in the error log on the AWS RDS dashboard or from within MySQL Workbench.
I have a local MySQL database (from which I exported the table data and moved the data to AWS RDS) on which the above-mentioned SQL works without issues.
