One example method includes performing replication operations and/or failure recovery operations for replication operations in a computing system using matrix clocks and replication controllers. The replication controller includes or has access to vectors of a matrix clock. The replication controller also includes a multiplexer. The multiplexer is configured as an m×n multiplexer using the matrix clock to determine m and n. The operation is performed using the configured multiplexer. This allows an imbalance of resources to be managed by the replication controller. The matrix clock can be updated, which may result in the multiplexer being reconfigured.

Failure recovery in a replication environment using a matrix clock and a replication controller

One example method includes performing replication operations and/or failure recovery operations for replication operations in a computing system using matrix clocks. Each node or process in a computing system is associated with a matrix clock that reflects streams required and/or available at the source and destination nodes. As the replication operation is performed, the matrix clocks are updated. When a failure is detected or when insufficient streams are available, the nodes may be throttled until sufficient streams are available. The matrix clocks facilitate a recovery line such that replication can resume when sufficient streams are available.
