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:
The default limit spec takes a limit and the list of columns to do an orderBy operation over. The grammar is:
{ "type" : "default", "limit" : <integer_value>, "columns" : [list of OrderByColumnSpec], }
OrderByColumnSpecs indicate how to do order by operations. Each order by condition can be a jsonString
or a map of the following form:
{ "dimension" : <Any dimension or metric>, "direction" : "ASCENDING OR DESCENDING" }
