Abstract: A particular node of a distributed state manager (DSM) detects a triggering condition for an initiation of a DSM initialization protocol. The particular node transmits a first bootstrap message to a second node of a proposed members list of a first proposed DSM configuration, comprising at least a joined members list and metadata indicative of state transitions for which processing of respective commit requests has been at least initiated at the particular node. In response to a determination that an initialization protocol for a particular DSM configuration indicated in a different bootstrap message received at the particular node has been completed, the particular nodes proposes itself as a coordinator of the particular DSM configuration based at least in part on an analysis of state transition metadata indicated in the different bootstrap message.

Abstract: A sequence of configuration-delta messages from a configuration manager of a replication graph established for replicating state information of an application is received at a particular node of the graph. Representations of the messages are stored in a local configuration change repository. Using the repository, the node identifies neighbor source nodes and destination nodes of the graph. Subsequent to receiving a particular configuration-delta message indicating that a neighbor source node has been removed from the graph, a different source node is identified by the particular node, and a request is sent to the different source node to transmit a set of state transition messages pertaining to the application.
