Headlines

RedisTimeSeries 1.12 adds a highly requested feature: insertion-filter for close samples. Many sensors report data periodically. Often, the difference between the measured value and the previous measured value is negligible and related to random noise or to measurement accuracy limitations. When both the time difference and the value difference between the current and the previous sample are small, it may be preferable to ignore (not to add) the new measurement.

What's new in 1.12

• #1543 insertion-filter for close samples:

  • Two new module configuration parameters are introduced: IGNORE_MAX_TIME_DIFF and IGNORE_MAX_VAL_DIFF.
  • Two new similar per-key parameters are introduced: ignoreMaxTimeDiff and ignoreMaxValDiff.
  • TS.ADD, TS.INCRBY, and TS.DECRBY now have a new optional argument: [IGNORE ignoreMaxTimeDiff ignoreMaxValDiff]. When creating a new time series, these two values are used to set the per-key parameters and override the two module configuration parameters. These values are ignored when specified with an existing time series.
  • [IGNORE ignoreMaxTimeDiff ignoreMaxValDiff] is also supported by TS.ALTER.
  • For each call to TS.ADD, if the following conditions are met:
    • series is not a compaction
    • the series' DUPLICATE_POLICY is LAST
    • timestamp ≥ max_timestamp
    • timestamp - max_timestamp ≤ ignoreMaxTimeDiff
    • abs(value - value_at_max_timestamp) ≤ ignoreMaxValDiff)) then this sample is ignored (not added) to the time series. max_timestamp is the maximal timestamp in the time series.
  • The same logic also applies for each call to TS.MADD based on the values of the per-key parameters.
  • When a sample is ignored, the returned value for TS.ADD and for the applicable array element in TS.MADD is max_timestamp.

Details

• Bug fixes (since 1.12-RC1)

  • #1607 Potential crash after deleting and recreating a source key of a compaction rule (MOD-7338)
  • #1610 COUNT argument accepts non-positive values (MOD-5413)

{{< note >}}

• The version inside Redis will be 1.12.2 in semantic versioning. Since the version of a module in Redis is numeric, we could not add a GA flag.
• Minimal Redis version: 7.4 {{< /note >}}
