Google, as you might expect, has massive amounts of data and it's built many tools to handle it. Stuff like MapReduce and GoogleFS, which spawned the open source Apache Hadoop, and BigTable, which spawned Apache HBase. But Google didn't stop with those projects. It's continued to create new big data tools and continues to publish papers about them.
Dremel (PDF) is designed to make querying the huge data sets stored in GoogleFS and BigTable much faster. Where a MapReduce job on Hadoop could take hours or even days, Dremel makes results available almost instantly.
