 * This class represents an active execution of a migration job. There can only

 *
 * Instances of this object is used as synchronization aid. A thread willing to
 * process a migration job creates an active execution in the database. The
 * database is setup with a unique index on migrationJobId. If creation is
 * successfull, the thread acquires the job, otherwise the thread looks for
 * another job. So, an ActiveExecution instance is also a lock record for the
 * corresponsing migration job.
