The default timing is every 5 minutes, however, this is not always going to be the case. Often the sync can run a bit longer depending on how much data may be coming down from the different systems. Learn more about what can cause long syncs here.
You can also customize this sync time if you don't want Bedrock to be pinging your systems every 5 minutes. This is a common setting for those who have API limits within their systems. Learn more about how to customize this setting here.
