Stateless processing of replicated state for distributed storage systems

Abstract

Embodiments are directed towards storing data in a storage system. A data controller may obtain a write request and write data from a client computer. A write message may be generated and provided to a data coordinator computer. The data coordinator may communicate the write message to a plurality of L-node computers. The data coordinator may obtain write confirmation messages from the L-node computers that indicate that the write data is stored. If enough write confirmation messages are obtained to indicate that a quorum is reached, the data coordinator may communicate a save confirmation message to the data controller. The data controller may generate a write acknowledgement message based on the save confirmation message provided by the data coordinator. The data controller may provide the write acknowledgement message to the client computer that made the original write request.
