Transactional replication allows subscribers to receive data in near-real time. ACID properties of transactions are maintained in transactional replication as well. Virtuoso implements the following flavors of transactional replication:

Ordinary transactional replicationOrdinary transactional replication flavor implements one-way data replication and is useful when data can be modified on only one server with other servers participating in replication providing read-only data access.
Bi-directional transactional replication Bi-directional transactional replication is useful when there is a requirement to allow data updates on multiple servers.
