PelatihA time bucket is one of the equal, aligned intervals into which a time axis is cut (the minutes of a day); bucketing assigns each record to its interval. Downsampling replaces the records of each bucket by a summary (the last value, the count, an open-high-low-close bar), storing or returning one row per bucket.
