Case Study: NK achieves sub-second analytics and fast, actionable insights with Actian Vectorwise

NK Transforms Big Data into Actionable Insights that Drive Business Success

NK.pl is Poland’s leading social network with about 13 million active users, generating massive click-stream and transactional data. NK struggled to keep up with rapidly changing member behavior because queries across its old transactional system (spread over 1,500 servers) could take weeks, leaving product and ad teams without timely insights needed to improve user experience and revenue.

NK built a new data warehouse that combines a Vectorwise-powered analytics engine on a single “fast” server with Hadoop for large-scale storage, chosen for its performance and cost-efficiency. The change enabled “speed-of-thought” analysis: teams now run 50–90 large queries daily with sub-second response times, ingest about 1 TB of new data per day, and use fast, actionable insights to drive product improvements and advertising revenue.
