How to interpret the duration of the purepath when it refers to multiple executions of the same SQL query? Is this the duration of all requests or the duration of a single request? In this case the purepath is the consequence of a consolidation because the queries were executed one after the other or because the pattern of the query was identified several times during the execution of the purepath?
The duration of the PurePath from start to end.
It is the wall-clock time (difference between start and end time), not the sum of all asynchronous executions.
