Nick stumbled into HBase in 2008 when his nightly ETL jobs started taking 20+ hours to complete. Since then, he has applied Hadoop and HBase to projects in social media, social gaming, click-stream analysis, climatology, and geographic data. Nick also helped establish Seattle’s Scalability Meetup and tried his hand at entrepreneurship. Most recently, he is an author on HBase in Action, available now. His has a passion for scalable access to scientific data.

We'll also look at the different factors that impact latency, including GC, cache misses, and system failures. Finally, the talk will highlight some of the work done in 0.96+ to improve the reliability of HBase. Read more.
