When we were building a big app 10 years back, we used ORM for user facing modules and stored procedure for batch processing such as CSV import/export. We would clear the ORM cache for every SP run which are usually scheduled at mid-night to avoid stale data.

These days, it is graph DB (such as firebase) for user facing module. It syncs data into a warehouse (such as BigQuery) that we use for batch processing.
