Sorting and limiting (groupBy)

    The limitSpec field provides the functionality to sort and limit the set of results from a groupBy query. If you group by a single dimension and are ordering by a single metric, we highly recommend using TopN Queries instead. The performance will be substantially better. Available options are:

    OrderByColumnSpec

    OrderByColumnSpecs indicate how to do order by operations. Each order-by condition can be a or a map of the following form:

    1. {
    2.     "direction" : <"ascending"|"descending">,
    3. }

    See Sorting Orders for more information on the sorting orders specified by “dimensionOrder”.
