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.
Dremel (PDF) is designed to make querying the huge data sets stored in GoogleFS and BigTable much faster.
