DatePart

class DatePart @InternalWowApi constructor(val field: QueryField<*>, val alias: String, val part: AggregationDatePart, val timeZone: String = "UTC", val dense: Boolean = false, val scope: AggregationGroupScope? = null) : AggregationGroup

Groups by one calendar part of the field's instant in timeZone, such as the weekday or the hour, so records from different days fall into one bucket. Keys are integers from AggregationDatePart's fixed domain; dense fills every key of that domain that has no records with the empty value of each metric.

Properties

alias

open override val alias: String

dense

val dense: Boolean

field

open override val field: QueryField<*>

The grouped field; null only for a TERMS or HISTOGRAM group whose input is an expression.

part

val part: AggregationDatePart

scope

open override val scope: AggregationGroupScope?

Where field is read when the query expands elements: null (the innermost element, relative to its container) or AggregationGroupScope.ROOT (a root field, by its absolute path), so a count of elements can be grouped by a field of the record they belong to, such as its creation day. Without elements both read the root.

timeZone

val timeZone: String
