An illustrative embodiment disclosed herein is an apparatus including a processor having programmed instructions to detect an operation associated with a first object instance in a first cluster, determine that the first object instance is configured for replication to a second cluster, create an object information (info) metadata entry for the first object instance, create an object replication metadata entry for the first object instance, and simultaneously write the object info metadata entry and the object replication metadata entry to a first data structure and a second data structure, respectively.

System and method for near-synchronous replication for object store

A system using pulsed leader consensus management that can manage storage by electing a leader node from a group of nodes and fulfilling read requests for the group of nodes if a sync state is not expired. The sync state can correspond to two conditions: first, that the nodes in the group direct the write requests for the group to the leader node; second, that a health pulse is detected, wherein the health pulse is generated if the leader node is alive (e.g. has not failed, terminated, or become non-responsive). If either of the two conditions fail, the sync state can be considered expired and the group of nodes may fall back to consensus-based read mechanisms, such as Paxos, until a new leader node is elected.
