Google has recently announced that its flagship wide-area database named Spanner has been made available on the Google Cloud. Google Spanner is the next generation globally-distributed database built inside Google and announced to the world through the paper published in OSDI 2012 . This article explores the implication of Google Spanner, in particular to the NoSQL world.
Several other distributed systems such as Kafka also implement Paxos algorithms indirectly by using Zookeeper. Zookeeper implements an atomic broadcast protocol (it has been shown that consensus and atomic broadcast are equivalent problems in distributed systems) known as Zookeeper Atomic Broadcast (ZAB) . Many NoSQL datastores, including HDFS and Hive, use Paxos algorithms as they store metadata in a Zookeeper cluster.
