Greenplum’s approach also avoids the need for a “loader” tier of servers, as required by some other MPP database vendors, which can add significant complexity and cost while. | F1 - The Fault-Tolerant Distributed RDBMS Supporting Google s Ad Go ogle Business Jeff Shute Mircea Oancea Stephan Ellner Ben Handy Eric Rollins Bart Samwel Radek Vingralek Chad Whipkey Xin Chen Beat Jegerlehner Kyle Littlefield Phoenix Tong SIGMOD May 22 2012 Today s Talk Gocgle F1 - A Hybrid Database combining the Scalability of Bigtable Usability and functionality of SQL databases Key Ideas Scalability Auto-sharded storage Availability Consistency Synchronous replication High commit latency Can be hidden o Hierarchical schema o Protocol buffer column types o Efficient client code Can you have a scalable database without going NoSQL Yes.
