Abstract: Embodiments of the present disclosure provide solutions for determining an elected search head captain is unqualified for the position, identifying a more qualified search head, and transferring the captain position to the more qualified search head. A method is provided that includes referencing qualification parameters in an elected search head captain, determining whether the newly elected search head captain is qualified for the position based on the parameters, identifying a more qualified search head to be the search head captain if the newly elected search head captain is determined to be unqualified for the position, and transferring the position of captain to the more qualified search head. The qualification parameters may include, for example, a pre-determined static flag set by an administrator of the search environment, and configuration replication status that corresponds to the most recent configuration state of the search head as recorded by the previous search head captain.

Abstract: Artifact life tracking storage techniques include performing an artifact request of an artifact at an artifact storage node. A current time to live (TTL) value is identified. A determination is made whether to increment a TTL flag of the artifact. Responsive to determining that the TTL tag should be incremented, the TTL flag is incremented to a subsequent value in a TTL extender list. Responsive to incrementing the TTL tag, the TTL modified tag value is set to the current time value.

Abstract: A processing node selects a first task from a task list and sends, to a task assignment repository, a first write operation with a first task identifier of the first task to assign the first task to the processing node. The processing node detects failure of the first write operation based on the first task already being assigned and selects a second task from the task list. The processing node sends, to the task assignment repository, a second write operation with a second task identifier of the second task to assign the second task to the processing node. The processing node detects success of the second write operation and executes the second task.
