Well that design is horrible. So you have your users and users_by_email and users_by_name table, and want to update a user’s email address, you have to, separately, update the users table, update the users_by_name table, delete from and insert into the users_by_email table (or will updating of the partition key work?). Can you at least make that whole mess atomic?

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
