Abstract
This specification provides a database system, and primary database election methods and apparatuses. The system includes at least one auxiliary node and a plurality of clusters. If any cluster is a primary database of the first table and the other clusters are standby databases: the primary database applies to all auxiliary nodes and all clusters for extension of a term of the primary database during the current term, and if the primary database obtains more than half of approval votes before the current term ends, the primary database determines that the term of the primary database is successfully extended, otherwise, the primary database downgrades itself to a standby database; and the auxiliary node and/or the clusters that don't record the primary database of the first table in term initiate a distributed election, and elect a cluster that obtains more than half of approval votes as a new primary database.
