Hi @jianqiao,
A quick question on Feature 1 using a vector-based aggregation: for a
group-by w/ a known bounded range (i.e., the min and max value), do we always
choose this approach over the hash-based, or depending on the range size (i.e.,
if the range is too wide, we may fall back to the hash-based)? Thanks!
