Abstract: Methods, systems and computer program products for computer system data management. A leader node that is in a leader-follower relationship with a follower node is deployed to manage metadata across a plurality of interconnected computing nodes of the computer system. Upon a failure of any sort that results in a loss of operation or a disconnection of the leader node, the followers undertake steps to bring up a new leader. Such steps to bring up a new leader include electing a new leader to replace the lost or disconnected leader and initializing the data state of the new leader node by causing the leader to request incremental snapshots from followers. Additional metadata that might have changed since closing the incremental snapshots can also be retrieved from the followers. The metadata that might have changed since the time of closing the incremental snapshot is subjected to verification using a consensus algorithm.

Abstract: Various embodiments set forth a computer-readable media storing program instructions that, when executed by one or more processors, cause the processors to perform steps of establishing, by a first node of a first cluster, a respective first connection with each of a plurality of second nodes in a second cluster; and establishing, by third node of the first cluster, a second connection with the first node. The third node is prevented from establishing a connection with any of the second nodes. The steps further include sending, by the third node, a message to the second cluster by sending the message to the first node via the second connection, where the first node is configured to forward the message to one of the second nodes via a corresponding one of the respective first connections.
