Question 1

How does the Attio into MongoDB direction work?

Accepted Answer

As a model sync with mapped document fields and paths, rather than as a bulk table replication. In practice that means you define the shape you want in Mongo and map Attio attributes onto it, which suits a document store better than a direct table copy would. It also means you choose exactly which attributes land where, so a nested Attio value can be written to a nested document path rather than arriving as an opaque blob.

Question 2

How are changes read out of MongoDB?

Accepted Answer

Through change streams, so an incremental run moves documents that actually changed rather than rescanning collections. Change streams need a replica set or sharded cluster, so a standalone deployment cannot use them. Schema is inferred by sampling recent documents, which handles most collections but can miss a field present on only a small fraction of them. Adding those fields manually before the first load is quicker than noticing the gap later.

Question 3

What can I write from MongoDB into Attio?

Accepted Answer

Any writable object in your workspace, including custom objects, plus list entries for adding records to a list. Identity matching does not need an Attio record identifier: an email address, a company domain, or a unique attribute holding your own Mongo document identifier all work. Modes are create, update, and create or update. Deleting Attio records or removing them from a list is not supported.

Question 4

Why connect a document database to a CRM?

Accepted Answer

Because the account context your go to market team needs usually lives in the application, not the CRM. Usage counts, plan state, onboarding progress and account structure are all in Mongo, and typing them into Attio by hand does not scale. Running reverse ETL keeps them current on the record automatically. The reverse direction matters less often, but suits teams who want CRM context available to services that already read from Mongo.
