Does executionTimeMillis include CPU time, disk access time, network time?

Hi Monika

As mentioned in the executionTimeMillis section of the explain output, it is the “Total time in milliseconds required for query plan selection and query execution. “.

This would count the time the server required to answer the query, but will not include the time it will take to communicate the result back to the client. That is, it will include CPU time, disk time, etc. but not network time.
