Abstract
Techniques for writing data in a distributed database system having a plurality of members and a master are disclosed. In one embodiment, a write request is received at an originating member. The write request is applied to a version of a database on the originating member and is placed in a journal queue of items for propagating to the master in one single atomic action. The write request is propagated to the master. Whether the propagated write request is associated with a conflict is determined, and in an event it is determined that the propagated write request is associated with the conflict, an indication that the write request is associated with the conflict is sent to the originating member.
