    • dateHistogram

      @Nullable public final DateHistogramGrouping dateHistogram()
      A date histogram group aggregates a date field into time-based buckets. This group is mandatory; you currently cannot roll up documents without a timestamp and a date_histogram group.

      API name: date_histogram

    • histogram

      @Nullable public final HistogramGrouping histogram()
      The histogram group aggregates one or more numeric fields into numeric histogram intervals.

      API name: histogram

    • terms

      @Nullable public final TermsGrouping terms()
      The terms group can be used on keyword or numeric fields to allow bucketing via the terms aggregation at a later point. The indexer enumerates and stores all values of a field for each time-period. This can be potentially costly for high-cardinality groups such as IP addresses, especially if the time-bucket is particularly sparse.
