Support getCount in HLLValue #188

Closed yarosman closed 3 years ago

yarosman commented 3 years ago

For example I want retrieve 30 records with bins ‘сlicks’, ‘shows’, ‘uniques_hll’. If I use batch request I can retrieve ‘clicks’, ‘shows’ and raw uniques_hll HLLValue. And after that for each key I have to execute operate HLLOperation.getCount additionally. Is it possible to add supporting getCount for HLLValue?

Same answer as I gave here: https://discuss.aerospike.com/t/hyperloglog-getcount-supports-in-batch-request/8386.

Adding batch read expressions that could perform the HLL getCount() on the server side with results being returned with the bins is something that has been discussed, but it's not currently on our roadmap. There is no guarantee if/when this functionality is implemented.
