LOBs may frequently use this wait state. Documented for informational purposes only. The scheduler is idle. The wait lets the worker tasks currently working on that population to complete or exit the current step.
Indicates that the log scans are running faster than the network sends. This is an issue only if network sends are slower than expected. This wait is for internal data structures and is usually is very short with no direct effect on data access.
Under normal conditions, this is not a customer issue because waits are expected here. This wait type guarantees that row versions are available before execution of a query under snapshot isolation.
A number of different message types use this wait type. This is an expected wait when partners change state or connection status. This is an expected wait if the log scan is caught up to the end of log or is reading from disk. The engine keeps a list of WSFC networks that is used in dynamic management views such as sys.
Tasks will usually be blocked when an update in that list is in progress. This is an expected wait, which can lengthen if the connection to the primary is slow to establish. This is an expected wait after failovers. Undo progress can be tracked through the Windows System Monitor perfmon.
This wait is also reflected by the Transaction Delay performance counter. This wait type is expected for synchronized availability groups and indicates the time to send, write, and acknowledge log to the secondary databases. This is an expected wait when a secondary database is catching up.
The processing of this request is always asynchronous, and there is a mechanism to remove redundant requests. There are also moments that this process is suspended because of configuration changes. All waits related with this listener synchronization mechanism use this wait type.
For example, for a task that runs every 10 seconds, after one execution, Always On Availability Groups waits about 10 seconds to reschedule the task, and the wait is included here. Used for the spinlock that grants access to it.In computing, scheduling is the method by which work specified by some means is assigned to resources that complete the work.
The work may be virtual computation elements such as threads, processes or data flows, which are in turn scheduled onto hardware resources such as processors, network links or expansion cards..
