Abstract: Certain embodiments described herein are directed to methods and systems for adding one or more nodes to a first cluster including a first node in a computer system. A method performed by the first node comprises receiving a first request from a second node to join the first cluster. The method also comprises retrieving a first cluster configuration associated with the first cluster from a distributed database through a first database server (DBS) and creating a second cluster configuration using the first cluster configuration and information received from the second node as part of the request. The method further comprises populating a first one or more local trust stores of a first one or more processes executing on the first node with a second one or more security certificates of a second one or more processes executing on the second node. The method further comprises writing the second cluster configuration to the distributed database and returning the second cluster configuration to the second node.

Abstract: Techniques for implementing dynamic timeout-based fault detection in a distributed system are provided. In one set of embodiments, a node of the distributed system can set a timeout interval to a minimum value and transmit poll messages to other nodes in the distributed system. The node can further wait for acknowledgement messages from all of the other nodes, where the acknowledgement messages are responsive to the poll messages, and can check whether it has received the acknowledgement messages from all of the other nodes within the timeout interval. If the node has failed to receive an acknowledgement message from at least one of the other nodes within the timeout interval and if the timeout interval is less than a maximum value, the node can increment the timeout interval by a delta value and can repeat the setting, the transmitting, the waiting, and the checking steps.

Abstract: Described herein are systems, methods, and software to enhance the management of data objects in a data storage system. In one implementation, a client in a data object environment is configured to identify a request for a data object in a first version from process on the client. Once the request is identified and the data object is provided or made available to the requesting process, the object storage system identifies a modification request for the data object to modify the data object from the first version to a second version. In response to the modification request, the object storage system generates an undo log entry to reflect the changes from the first version to the second version and updates the data object to the second version.
