REDUCE framework groups Geo Time Series™ by equivalence classes based on label values and applies a function on each equivalence class of Geo Time Series™, considering the values of each tick and producing one GTS per equivalence class.
As the selected reducer function is applied tick by tick, it is usually wise to
BUCKETIZE the GTS first with a common value of
The labels whose values are common to all the GTS in an equivalence class will be retained.
If all the inputs are bucketized with the same bucket span and bucket end, the output of reduce will be bucketized too. Use
UNBUCKETIZE if needed after
Since 2.1 you can make REDUCE override the GTSs ticks. This usage in mainly to be used in conjuction with
