There is no syntactical difference between Aurora/MySQL and regular MySQL until you start interacting with S3.
Also if you’re using only the subset of MySQL that is supported by SQLite, you’re missing out on some real optimizations for bulk data loads like “insert into ignore...” and “insert...on duplicate key update...”. Besides that, the behavior of certain queries/data types/constraints are inconsistent between MySQL and every other database in existence.
Finally, you can’t really do performance testing across databases.
