To be more precise : We have a database with more than 400 Gb and ONE table

runs, it writes a lot on the disks in temporary file (although we have 128
GB of Ram...). Of course, each table is well indexes...
That is why I'm thinking about replication : My server A (master) is for my
users... and my server B is a server reserved for calculations (and this
server B which writes on the base)
This is a image of my dream system :

what happens when master A continues to update/insert into these tables
that your cron job is batch updating on the offline copy ? How would you
merge those changes in ?
