In distributed storage environments, nodes may send replicated writes for temporal volumes and may be configured to request on-demand consistency intervals in order to allow multiple nodes to transition between timestamps for temporal data in a uniform and coordinated manner. In response to a request from a node for a consistency interval transition, a consistency interval coordinator may end a current consistency interval and start another and may provide coordination to various nodes to enable the nodes to transition from one timestamp to another, and thus from one temporal version to another, while prevent data corruption or inconsistency between the temporal versions. Additionally, periodic consistency intervals may be utilized to provide consistent and coordinated transitions between temporal timestamps. In some embodiments, replicated writes including temporal timestamp information may be stored persistent spillover logs allowing offline updating and versioning of data to temporal volumes.
