Hi, all Continue this topic, I am bit of confused whether I should implement the hyperloglog in storm or perform the postgresql-hll extension in postgresDB, if I can effectively count the uniques in postgresql-hll, and write into a separate distinct count table, why would I implement that in storm? I know some developers are implementing hll in storm, and I am just unclear what the advantage to do that in storm than in database with hll-extension.
