TopNMetricSpec
Specifies how topN values should be sorted.
Numeric TopNMetricSpec
Indicates the metric to sort topN results by, e.g. “count” in this example:
"metric": {
"type": "numeric",
"metric": "count"
}Dimension TopNMetricSpec
This metric specification sorts TopN results by dimension value.
"metric": {
"type": "dimension",
"ordering": "lexicographic",
"previousStop": "<previousStop_value>"
}Possible sorting orders are:
| Ordering | Description |
|---|---|
lexicographic | Sorts values by converting Strings to their UTF-8 byte array representations and comparing lexicographically, byte-by-byte. |
alphanumeric | Suitable for strings with both numeric and non-numeric content. file12 sorts after file2. |
numeric | Sorts values as numbers. |
strlen | Sorts values by their string lengths. When there is a tie, this comparator falls back to using the String compareTo method. |
version | Sorts values as versions. 10.0 sorts after 9.0, 1.0.0-SNAPSHOT sorts after 1.0.0. |
previousStop is an optional string and the starting point of the sort. For example, if a previousStop value is b, all values before b are discarded. This field can be used to paginate through all the dimension values.
Inverted TopNMetricSpec
Inverts the order of the delegate metric spec and sorts dimension values in inverted order. It can be used to sort the values in ascending order.
"metric": {
"type": "inverted",
"metric": <delegate_top_n_metric_spec>
