Sandeep Narayanaswami commented on APEXMALHAR-2094:
---------------------------------------------------
[~thw] Thomas, I do intend to add more functionality. DataSketches includes
algorithms like hyperloglog, and heavy hitters / frequent items and a "theta
sketch" framework that will allow set operations on multiple streams, and I
want to build Apex operators for each of these.
By "module", do you mean a package like {{statistics}} or {{algo}} in the
Malhar library? If so, yes, it might make sense to move this operator from
{{statistics}} into a {{sketches}} package that will encapsulate all stream
sketching algorithms.
