Backport of #127849 to 8.19.
Currently, time-series aggregations use the
values
aggregation to collect dimension values. While we might introduce a specialized aggregation for this in the future, for now, we are usingvalues
, and the inputs are likely ordinal blocks. This change speeds up thevalues
aggregation when the inputs are ordinal-based.Execution time reduced from 461ms to 192ms for 1000 groups.
