Overview

This synchronization process is defined in the pipeline batch CRM Contacts to xDB Sync Pipeline Batch.

The contact synchronization process involves the following steps:

1. Read contacts from CRM.
2. Loop through the contacts from CRM. For each contact:
   1. Get the xDB contact that corresponds to the CRM contact if one exists, otherwise create a new xDB contact.
   2. Get the entry from the work queue that corresponds to the xDB contact if one exists, otherwise create a new work queue entry.
   3. Apply value mappings by reading values from the CRM contact and writing those values to the work queue entry.

3. Read contacts from work queue.
4. Create a known contact set for the xDB bulk contact update API.
5. Loop through the contacts from the work queue. For each contact:

1. Add the contact to the known contact set.

6. Submit the known contact set.
