Abstract
A node failure detector for use in a distributed database that is accessed through a plurality of interconnected transactional and archival nodes. Each node is selected as an informer node that tests communications with each other node. Each informer node generates a list of suspicious nodes that is resident in one node designated as a leader node. The leader node analyzes the data from all of the informer nodes to designate each node that should be designated for removal with appropriate failover procedures.
