    Starts an experiment run with a given set of executions to run.

    Starts an experiment run with a given set of executions to run.

    executionsToRun

    a list of executions to run.

    includeBreakdown

    If it is true, breakdown results of an execution will be recorded. Setting it to true may significantly increase the time used to run an execution.

    iterations

    The number of iterations to run of each execution.

    variations

    Variations used in this run. The cross product of all variations will be run for each execution * iteration.

    tags

    Tags of this run.

    timeout

    wait at most timeout milliseconds for each query, 0 means wait forever

    returns

    It returns a ExperimentStatus object that can be used to track the progress of this experiment run.
