Degree of Parallelism (7.0 Insert) Event Class
The Degree of Parallelism (7.0 Insert) event class occurs each time SQL Server executes a SELECT, INSERT, UPDATE, or DELETE statement.
When this event class is included in a trace, the amount of entailed overhead may significantly impede performance if these events occur frequently. To minimize overhead incurred, limit use of this event class to traces that briefly monitor specific problems.
