Do you have insights into how to improve spark? Are you thinking about how to move from batch to real-time? Do you get excited about data layout? Distributed fault tolerance and consistency? If so, this might be the team for you.
At Quantcast, data is king, and the Modeling Platform Infrastructure team knows how to process it. The unique features of our custom map-reduce implementation include a revolutionary petabyte sort mechanism, an efficient and flexible petabyte join and lookup, based on innovative data indexing and partitioning mechanisms, dynamic task size adjustment in running jobs, and a self-tuning system that learns and improve job performance without developer intervention. In the last 5 years, it has allowed Quantcast to scale from processing 400 to 40,000 terabytes of data per day. For a workload consisting primarily of ETL, analytics, and data mining, our processing platform is on average 4 to 5 times more efficient than the most popular open-source map-reduce system.
