(English Abstract)
This paper proposes a method to improve the performance of Binary Bernoulli Sampling (BBS). BBS is a sampling technique suitable for a multi-source stream environment. Accordingly, a recent approach has been proposed for distributed processing of BBS based on Apache Storm, with a multi-coordinator structure. However, this approach causes an additional coordinator waiting problem, which limits the performance improvement. In this paper, we solve the coordinator waiting problem by introducing a multi-distribution structure and a distributor separation structure. The multidistribution structure enables multiple coordinators, rather than one, to participate in the distribution, minimizing the coordinator waiting time. The distributor separation structure moves the distributing function from the coordinators to the distributors, maximizing the processing performance. We perform various experiments by implementing our proposed structure on the Storm-based distributed BBS. The experimental results show that our structure improves the performance by up to 90 times compared to the previous distributed BBS.
