Materialized View Refresh - NUM_JOINS_THRESHOLD_EXCEEDED?

[GregTyndall]

I have a very basic view with 3 inner joins that will only do a full refresh. Is there a limit to the number of joins you can have and still get an incremental refresh?

"incrementalization_issues": [
{
"issue_type": "INCREMENTAL_PLAN_REJECTED_BY_COST_MODEL",
"prevent_incrementalization": true,
"cost_model_rejection_subtype": "NUM_JOINS_THRESHOLD_EXCEEDED"
}
]

Thanks!
