Cumulative Cardinality Aggregation Usage
editCumulative Cardinality Aggregation Usage
editFluent DSL example
edita => a .DateHistogram("projects_started_per_month", dh => dh .Field(p => p.StartedOn) .CalendarInterval(DateInterval.Month) .Aggregations(aa => aa .Cardinality("commits", sm => sm .Field(p => p.NumberOfCommits) ) .CumulativeCardinality("cumulative_commits", d => d .BucketsPath("commits") ) ) )
Object Initializer syntax example
editnew DateHistogramAggregation("projects_started_per_month") { Field = "startedOn", CalendarInterval = DateInterval.Month, Aggregations = new CardinalityAggregation("commits", "numberOfCommits") && new CumulativeCardinalityAggregation("cumulative_commits", "commits") }
Example json output.
{ "projects_started_per_month": { "date_histogram": { "field": "startedOn", "calendar_interval": "month" }, "aggs": { "commits": { "cardinality": { "field": "numberOfCommits" } }, "cumulative_commits": { "cumulative_cardinality": { "buckets_path": "commits" } } } } }
Handling Responses
editresponse.ShouldBeValid(); var projectsPerMonth = response.Aggregations.DateHistogram("projects_started_per_month"); projectsPerMonth.Should().NotBeNull(); projectsPerMonth.Buckets.Should().NotBeNull(); projectsPerMonth.Buckets.Count.Should().BeGreaterThan(0); foreach (var item in projectsPerMonth.Buckets) { var commitsDerivative = item.CumulativeCardinality("cumulative_commits"); commitsDerivative.Should().NotBeNull(); commitsDerivative.Value.Should().NotBe(null); }
