For queries executed in parallel mode, the distribution of threads is shown as a bar diagram.
The graphical representation for threads shows the maximum number of active threads during the execution time of the query. The internal operator ID, which is included on the query tree diagram, shows the distribution and number of threads per operator.
In this diagram, the second column represents a particular section of the query execution
time. The operator ID shows how many threads are being used. For example:
- Operator 01 is using six threads.
- Operator 03 is using one thread.
