Default synchronization time in sql alwayson 2014


1. Can you please tell me what is the Default synchronization time in sql alwayson 2014 from primary node to secondary node. Is there any TSQL query to check this?

2. And if running a select statement against the cluster name, is there a chance that the passive node will take the statement into execution and report data without being synchronized with the primary node ?

1. - There's no default time set. For synchronous replication is immediate and for asynchronous replication there's no default value set (Microsoft didn't release any information on this subject) so it will depends on the network speed and servers workload but I will say less than a second based on my own tests and experience.

2. - Cluster name? Don't you mean Listener name? Yes, that's possible only for asynchronous replications but I think it's only on theory because I never saw that behaviour (see why in my previous comment).
