As it can be seen in https://docs.google.com/spreadsheets/d/19iSNSc_lNlzWRe_0_R937E7af2ekjXPZur0sog5Fj4U/edit?usp=sharing "nGroups scalability trend" sheet, as the number of groups in data increases, SBE $group perf gain decreases dramatically. Investigate whether this issue is legit and if so, improve the scalability in terms of number of groups in data. |
