TS.MREVRANGE

is start timestamp for the range query (integer UNIX timestamp in milliseconds) or - to denote the timestamp of the earliest sample in the time series.

is end timestamp for the range query (integer UNIX timestamp in milliseconds) or + to denote the timestamp of the latest sample in the time series.

uses these filters:

• label=value, where label equals value
• label!=value, where label does not equal value
• label=, where key does not have label label
• label!=, where key has label label
• label=(_value1_,_value2_,...), where key with label label equals one of the values in the list
• label!=(value1,value2,...), where key with label label does not equal any of the values in the list

is used when a time series is a compaction. With LATEST, TS.MREVRANGE 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.MREVRANGE does not report the latest possibly partial bucket. When a time series is not a compaction, LATEST is ignored.

The data in the latest bucket of a compaction is possibly partial. A bucket is closed and compacted only upon arrival of a new sample that opens a new latest bucket. There are cases, however, when the compacted value of the latest possibly partial bucket is also required. In such a case, use LATEST.

filters samples by a list of specific timestamps. A sample passes the filter if its exact timestamp is specified and falls within [fromTimestamp, toTimestamp].

filters samples by minimum and maximum values.

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 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.

limits the number of returned samples.

is a time bucket alignment control for AGGREGATION. It controls the time bucket timestamps by changing the reference timestamp on which a bucket is defined.

Values include:

• start or -: The reference timestamp will be the query start interval time (fromTimestamp) which can't be -
• end or +: The reference timestamp will be the query end interval time (toTimestamp) which can't be +
• A specific timestamp: align the reference timestamp to a specific time

Note: When not provided, alignment is set to 0.

aggregates results into time buckets, where:

• aggregator takes one of the following aggregation types:

  aggregator	Description
  avg	Arithmetic mean of all values
  sum	Sum of all values
  min	Minimum value
  max	Maximum value
  range	Difference between the highest and the lowest value
  count	Number of values
  first	Value with lowest timestamp in the bucket
  last	Value with highest timestamp in the bucket
  std.p	Population standard deviation of the values
  std.s	Sample standard deviation of the values
  var.p	Population variance of the values
  var.s	Sample variance of the values
  twa	Time-weighted average of all values (since RedisTimeSeries v1.8)

• bucketDuration is duration of each bucket, in milliseconds.

Without ALIGN, bucket start times are multiples of bucketDuration.

With ALIGN align, bucket start times are multiples of bucketDuration with remainder align % bucketDuration.

The first bucket start time is less than or equal to fromTimestamp.

controls how bucket timestamps are reported.

is a flag, which, when specified, reports aggregations also for empty buckets.

Regardless of the values of fromTimestamp and toTimestamp, no data is reported for buckets that end before the earliest sample or begin after the latest sample in the time series.

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 reducer type used to aggregate series that share the same label value.

  reducer	Description
  avg	per label value: arithmetic mean of all values (since RedisTimeSeries v1.8)
  sum	per label value: sum of all values
  min	per label value: minimum value
  max	per label value: maximum value
  range	per label value: difference between the highest and the lowest value (since RedisTimeSeries v1.8)
  count	per label value: number of values (since RedisTimeSeries v1.8)
  std.p	per label value: population standard deviation of the values (since RedisTimeSeries v1.8)
  std.s	per label value: sample standard deviation of the values (since RedisTimeSeries v1.8)
  var.p	per label value: population variance of the values (since RedisTimeSeries v1.8)
  var.s	per label value: sample variance of the values (since RedisTimeSeries v1.8)

Notes:

• The produced time series is named <label>=<groupbyvalue>
• The produced time series contains two labels with these label array structures:
  • reducer, the reducer used
  • source, the time series keys used to compute the grouped series (key1,key2,key3,...)

Create two stocks and add their prices at three different timestamps.

2) (integer) 1010
3) (integer) 1020

You can now retrieve the maximum stock price per timestamp.

The FILTER type=stock clause returns a single time series representing stock prices. The GROUPBY type REDUCE max clause splits the time series into groups with identical type values, and then, for each timestamp, aggregates all series that share the same type value using the max aggregator.

Create two stocks and add their prices at nine different timestamps.

Now, for each stock, calculate the average stock price per a 1000-millisecond timeframe, and then retrieve the stock with the maximum average for that timeframe in reverse direction.

Query all time series with the metric label equal to cpu, then group the time series by the value of their metric_name label value and for each group return the maximum value and the time series keys (source) with that value.
