Abstract: Certain embodiments described relate 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 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 a second node as part of a request to join the first cluster. 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: Certain aspects described herein are directed to methods and systems for updating a status of a first process. In certain aspects, a method includes periodically examining a first table stored in a consistent and distributed database, wherein the table includes a first indication of a status of the first process and a second indication of a status of a second process and the first process and the second process are clustered for implementing functions of a distributed application in a distributed manner. The method further includes determining that the first indication has not changed during a first time period and changing the status of the first process in a second table to reflect that the first process is non-operational, wherein a different share of workload associated with the distributed application is performed by the second process as compared to when the first process was operational.

Abstract: Various aspects are disclosed for distributed application management using an embedded persistent queue framework. In some aspects, task execution data is monitored from a plurality of task execution engines. A task request is identified. The task request can include a task and a Boolean predicate for task assignment. The task is assigned to a task execution engine embedded in a distributed application process if the Boolean predicate is true, and a capacity of the task execution engine is sufficient to execute the task. The task is enqueued in a persistent queue. The task is retrieved from the persistent queue and executed.
