I'm looking to use a Craft3 installation as a bridge app to synch a client's contacts from their CRM server to their Email Service Provider, via respective APIs.
I'll be storing their contacts as users in Craft. They have four contact lists with numbers (there may be some overlap) totaling:
- 12,000 contacts
- 55,000 contacts
- 23,000 contacts
- 22,000 contacts
Is storing these in Craft as users a realistic option? We'll be editing/adding new users in small batches on a daily basis, slicing them off the full list on the source side by last updated date, and then filtering records to push to the destination using the Craft API.
