Recently, I was working on a MySQL support ticket where a customer was facing an issue while transporting tablespace from MySQL 5.6 to MySQL 5.7.

ERROR 1808 (HY000): Schema mismatch (Table flags don't match, server table has 0x10 and the meta-data file has 0x1)

There are both direct and indirect costs associated with allowing these unhealthy systems to continue to exist. Let’s look at some.

A common way of ensuring backups occur in AWS is to setup ebs snapshots of the slave. In terms of usage, let us assume your CPU is about 50% used and you have about 20GB of hot data that needs to stay in the memory for the database.

If we look at what this …
