| limitspec | Sort groupBy query results |
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:
DefaultLimitSpec
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],
}
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 name>",
"direction" : <"ascending"|"descending">,
"dimensionOrder" : <"lexicographic"(default)|"alphanumeric"|"strlen"|"numeric">
}
If only the dimension is provided (as a JSON string), the default order-by is ascending with lexicographic sorting.
See Sorting Orders for more information on the sorting orders specified by "dimensionOrder".
