TS.CREATERULE

Create a compaction rule.

TS.CREATERULE sourceKey destKey AGGREGATION aggregator bucketDuration [alignTimestamp]

• sourceKey - Key name for source time series

• destKey - Key name for destination (compacted) time series

• AGGREGATION aggregator bucketDuration

  Aggregate results into time buckets.

  • aggregator - Aggregation type: One of the following:

    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	the value with the lowest timestamp in the bucket
    last	the value with the 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

  • bucketDuration - duration of each bucket, in milliseconds
  • alignTimestamp - alignment of the compacted buckets start times

  The alignment of time buckets is 0.

destKey should be of a timeseries type, and should be created before TS.CREATERULE is called.

Notes:

• Calling TS.CREATERULE with a nonempty destKey can result in an undefined behavior
• Samples should not be explicitly added to destKey
• Only new samples that are added into the source series after the creation of the rule will be aggregated
