  • Patent number: 11882054
    Abstract: A system of terminating data server nodes based on insufficient processing of messages. In embodiments, a plurality of time-stamped, searchable events from machine data are created. A plurality of data server nodes that service messages across one or more portions of the plurality of time-stamped, searchable events, are executed in parallel. For each message received, the message is sent to a data server node, of the plurality of data server nodes, to cause the receiving data server node to perform a data operation associated with the received message. A determination can then be made that a particular data server node insufficiently processes messages sent to the particular data server node. Thereafter, termination of the particular data server node is initiated to terminate processes or threads executed by the particular data server node.

  • Patent number: 10911369
    Abstract: A system of dynamically-instantiated data server components provides access to a data repository. Different data server components are assigned to different data collections in the repository. A distribution component receives messages and, based on data collection identifiers associated with the messages, routes the messages to corresponding data server components. Based on the messages, the data server components perform data operations with respect to their corresponding data collections. Data server components may be terminated when their assigned data collections are not in use. When an incoming message is associated with a data collection for which no data server component exists, the distribution component dynamically instantiates a new data server component for the data collection. In an embodiment, data server components make working copies of their respectively assigned data collections in a high-speed memory.
