Big amount of users to sync

Hello guys,

Looking for help and advices on big data sync between WP and SF.

I expect to have around 100k active WP users in average per month that has to be synced with SF CRM which has 500k contacts/accounts by now. Ideally it should be live sync but because of the amount of data – I think it’s not going to be achievable (mostly API limit is the “bottle neck”).

1. Lets make the job simpler and agree that Single Point of Truth will be WP and I’ll push data to SF only, so not synced both ways.

2. The next idea is to use some “prevent method” from pushing data to SF on any user update. I mean check some specific fields that I want to sync before pushing to SF. Maybe using this: https://github.com/MinnPost/object-sync-for-salesforce/blob/master/docs/extending-sync-allowed.md#push So if the field update is not needed for sync – skip the sync to SF.

3. Maybe have a JSON object to send all data to SF and then parse it on SF side with APECS and SF triggers?

Is there any other ideas guys or suggestions on how to make sync for lots of users with this plugin? Maybe someone has this problem before? Maybe you did some custom triggers?

P.S. CRON is not a good option for me as data has to be “live synced”.

Thanks everyone for help and I’ll keep you posted with my research.
