Stats Bucket Aggregation Usageedit
Fluent DSL exampleedit
a => a
.DateHistogram("projects_started_per_month", dh => dh
.Field(p => p.StartedOn)
.Interval(DateInterval.Month)
.Aggregations(aa => aa
.Sum("commits", sm => sm
.Field(p => p.NumberOfCommits)
)
)
)
.StatsBucket("stats_commits_per_month", aaa => aaa
.BucketsPath("projects_started_per_month>commits")
)
Object Initializer syntax exampleedit
new DateHistogramAggregation("projects_started_per_month")
{
Field = "startedOn",
Interval = DateInterval.Month,
Aggregations = new SumAggregation("commits", "numberOfCommits")
}
&& new StatsBucketAggregation("stats_commits_per_month", "projects_started_per_month>commits")
