Who is Sanjay Ghemawat?
Sanjay Ghemawat was born in West Lafayette, Indiana, in 1966 to an Indian-origin family. He did his undergraduate degree from Cornell University in 1987, and later earned a PhD in 1995 from the Massachusetts Institute of Technology (MIT) with a dissertation titled The Modified Object Buffer: A Storage Management Technique for Object-Oriented Databases.
Before Google even existed, Ghemawat worked at the DEC Systems Research Center, where he met Jeff Dean, who worked at another DEC research lab nearby. Dean joined Google first, and Ghemawat followed in 1999.
Together, they worked on several projects, including Google File System (GFS), MapReduce in 2004, which helped Google process enormous amounts of data, Hadoop, Bigtable with development of popular NoSQL databases, including HBase and Apache Cassandra, and Spanner, the world's first database.
