Dynamic replication peering

A distributed database system may comprise a master computing node and one or more replication peer nodes. Upon identifying a failure of one of the nodes, a control plane may obtain a computing node instance and configure the computing node instance to act as a log-only peer to the remaining nodes....

More Information
Summary:A distributed database system may comprise a master computing node and one or more replication peer nodes. Upon identifying a failure of one of the nodes, a control plane may obtain a computing node instance and configure the computing node instance to act as a log-only peer to the remaining nodes. The log-only peer may store the log tail of the master computing node and may participate in quorum decisions. Upon restoration of the failed node, the log-only peer may be returned to the pool of computing node instances.
