Wait statistics, in the context of SQL Server, refer to the amount of time that a query spends waiting to access data in the database. When a client application requests data from the database, the request is placed in a queue and the client application must wait for its turn to access the data. The time that the query spends waiting is called a "wait" and is tracked by SQL Server. This information can be used to identify potential performance bottlenecks and optimize the performance of the database. Wait statistics are commonly used by database administrators to diagnose and troubleshoot performance issues in SQL Server.


The SOS_WORK_DISPATCHER wait type in SQL Server is a type of wait that occurs when a task is waiting for a worker to become available. In SQL Server, workers are used to execute tasks, such as queries or index operations. When a task is in the SOS_WORK_DISPATCHER wait state, it is waiting for a worker to become available so that it can be executed. This wait type is typically only seen when there are not enough workers available to execute all of the tasks that are waiting to be executed.
