    • Method Detail

      • latest

        public MRangeArgs latest()
        Used when a time series is a compaction. With LATEST, TS.MRANGE also reports the compacted value of the latest possibly partial bucket, given that this bucket's start time falls within [fromTimestamp, toTimestamp]. Without LATEST, TS.MRANGE does not report the latest possibly partial bucket. When a time series is not a compaction, LATEST is ignored.
        Returns:
        the current MRangeArgs
      • filterByTimestamp

        public MRangeArgs filterByTimestamp​(long... timestamps)
        Filters samples by a list of specific timestamps. A sample passes the filter if its exact timestamp is specified and falls within [fromTimestamp, toTimestamp].
        Parameters:
        timestamps - the timestamps
        Returns:
        the current MRangeArgs
      • filterByValue

        public MRangeArgs filterByValue​(double min,
                                        double max)
        Filters samples by minimum and maximum values.
        Parameters:
        min - the min value of the sample
        max - the max value of the sample
        Returns:
        the current MRangeArgs
      • withLabels

        public MRangeArgs withLabels()
        Includes in the reply all label-value pairs representing metadata labels of the time series. If WITHLABELS or SELECTED_LABELS are not specified, by default, an empty list is reported as label-value pairs.
        Returns:
        the current MRangeArgs
      • selectedLabels

        public MRangeArgs selectedLabels​(String... labels)
        Returns a subset of the label-value pairs that represent metadata labels of the time series. Use when a large number of labels exists per series, but only the values of some of the labels are required.

        If WITHLABELS or SELECTED_LABELS are not specified, by default, an empty list is reported as label-value pairs.

        Parameters:
        labels - the set of labels to select
        Returns:
        the current MRangeArgs
      • count

        public MRangeArgs count​(int count)
        Limits the number of returned samples.
        Parameters:
        count - the max number of samples to return
        Returns:
        the current MRangeArgs
      • align

        public MRangeArgs align​(long timestamp)
        Set the time bucket alignment control for AGGREGATION. It controls the time bucket timestamps by changing the reference timestamp on which a bucket is defined.
        Parameters:
        timestamp - the timestamp
        Returns:
        the current MRangeArgs
      • alignUsingRangeStart

        public MRangeArgs alignUsingRangeStart()
        Set the time bucket alignment control for AGGREGATION to the query start interval time (fromTimestamp). It controls the time bucket timestamps by changing the reference timestamp on which a bucket is defined.
        Returns:
        the current MRangeArgs
      • alignUsingRangeEnd

        public MRangeArgs alignUsingRangeEnd()
        Set the time bucket alignment control for AGGREGATION to the query end interval time (toTimestamp). It controls the time bucket timestamps by changing the reference timestamp on which a bucket is defined.
        Returns:
        the current MRangeArgs
      • aggregation

        public MRangeArgs aggregation​(Aggregation aggregation,
                                      Duration bucketDuration)
        Aggregates results into time buckets.
        Parameters:
        aggregation - the aggregation function, must not be null
        bucketDuration - the duration of each bucket, must not be null
        Returns:
        the current MRangeArgs
      • bucketTimestamp

        public MRangeArgs bucketTimestamp​(BucketTimestamp ts)
        Controls how bucket timestamps are reported.
        Parameters:
        ts - the bucket timestamp configuration, must not be null
        Returns:
        the current MRangeArgs
      • empty

        public MRangeArgs empty()
        When specified, reports aggregations also for empty buckets.
        Returns:
        the current MRangeArgs
      • groupBy

        public MRangeArgs groupBy​(String label,
                                  Reducer reducer)
        Aggregates results across different time series, grouped by the provided label name. When combined with AGGREGATION the groupby/reduce is applied post aggregation stage.

        label is label name to group a series by. A new series for each value is produced. reducer is the reducer type used to aggregate series that share the same label value.

        Parameters:
        label - the label, must not be null
        reducer - the reducer function, must not be null
        Returns:
        the current MRangeArgs
      • getGroupByClauseArgs

        public List<String> getGroupByClauseArgs()
