I have a MySQL-DB containing 2 tables "records" and "features" linked by one foreign key in features referring to the primary key "id" in records.



My goal is to create a randomized but fixed subset of the data in the DB for machinelearning that can be dumped and hashed for reproducability.



So I thought it would be handy if I could draw a randomized subset of the data and move it to a seperate DB.



Is that possible and if yes: how?
