Examples with ManagedPrimaryElectionService io.atomix.primitive.partition.ManagedPrimaryElectionService used on opensource projects

Example 1 with ManagedPrimaryElectionService

use of io.atomix.primitive.partition.ManagedPrimaryElectionService in project atomix by atomix.

the class Atomix method start.

/**
 * Starts the Atomix instance.
 * <p>
 * The returned future will be completed once this instance completes startup. Note that in order to complete startup,
 * all partitions must be able to form. For Raft partitions, that requires that a majority of the nodes in each
 * partition be started concurrently.

 * @return a future to be completed once the instance has completed startup
