Hi gents, was taking a look to the ways to calculate distinct count per facet.
Reading through Yonik blogs [1] it seems quite safe to assume the " unique(field)" is the approach to go. Do we have any benchmark or details about the implementation ? Because as per Yonik blog it is faster than HyperLogLog so I assume it is using different data structures and algorithms. Worst case scenario I go through the code, but any presentation or blog would be useful!
