@Deprecated public DateHistogramGroupConfig(String field, DateHistogramInterval interval, @Nullable DateHistogramInterval delay, @Nullable String timeZone) Deprecated.Build a DateHistoConfig usingDateHistogramGroupConfig.CalendarInterval
orDateHistogramGroupConfig.FixedInterval
insteadCreate a newDateHistogramGroupConfig
using the given configuration parameters.The
field
andinterval
are required to compute the date histogram for the rolled up documents. Thedelay
is optional and can be set tonull
. It defines how long to wait before rolling up new documents. ThetimeZone
is optional and can be set tonull
. When configured, the time zone value is resolved using (DateTimeZone.forID(String)
and must match a time zone identifier provided by the Joda Time library.- Parameters:
field
- the name of the date field to use for the date histogram (required)interval
- the interval to use for the date histogram (required)delay
- the time delay (optional)timeZone
- the id of time zone to use to calculate the date histogram (optional). Whennull
, the UTC timezone is used.- Since:
- 7.2.0

validate
Description copied from interface:Validatable
Perform validation. This method does not have to be overridden in the event that no validation needs to be done, or the validation was done during object construction time. AValidationException
that is not null is assumed to contain validation errors and will be thrown.- Specified by:
validate
in interfaceValidatable
- Returns:
- An
Optional
ValidationException
that contains a list of validation errors.
