Is anyone experiencing Marketo to Salesforce sync delays? Started yesterday and is continuing to happen. Tested multiple forms and nothing is coming through. Not even close to Salesforce API limit. Made no changes to form affected either.
Before yesterday, SFDC sync was under 5mins.
Have you made any major updates to SF or Marketo (changes in either system will have to sync both directions)... Also, how many records in your DB? "Long syncs" are sort of a relative term depending on the number of records that you have.
You can submit a support ticket to have them take a look at what kind of a backlog you're looking at - they will be able to tell you how many records are trying to update and a rough estimate of timeframe.
One thing you can do to circumvent the leads not getting passed over is putting a sync to salesforce flow step in your crucial programs - this is a separate call from the salesforce sync and will push the individual lead update faster than waiting up to a few hours for a sync.
It creates another API call. I am not sure if that lead will still be packaged in the sync update (my guess is that it is), but the later sync will not overwrite with old information if that is your concern. It's not really a duplicate in that one is an individual call and the sync is a large batch (up to 10k per record type, i believe).
