Abstract:
Systems and methods for search result replication in a search head cluster of a data aggregation and analysis system. An example method may comprise maintaining a replication count in a data store associated with at least one of the plurality of search heads, the replication count corresponding to how many of the replicas of the search result are stored in the search head cluster, determining that the replication count is greater than a target replication count, based on determining that the replication count is greater than the target replication count, initiating a deletion of at least one replica of the replicas of the search result from a target search head of the plurality of search heads storing the replicas, receiving an indication that the deletion is complete, and based on receiving the indication that the deletion is complete, decreasing the replication count corresponding to the search result.

Systems and methods for search result replication in a search head cluster of a data aggregation and analysis system. An example method may comprise maintaining a replication count corresponding to how many replicas of a result of a particular map-reduce search exist in a search head cluster comprising a plurality of search heads that are each configured to enable them to manage a reduce phase of a map-reduce search, determining that the replication count is less than a target replication count, selecting, based the determining, a target search head from the search head cluster to receive a replica of the search result, initiating a replication of the search result from a source search head in the search head cluster to the selected target search head, receiving an indication that the replication is complete, and based on receiving the indication, increasing the replication count corresponding to the search result.
Abstract:
A high availability scheduler of tasks in a cluster of server devices is provided. A server device of the cluster of server devices enters a leader state based upon the results of a consensus election process in which the server device participates with others of the cluster of server devices. Upon entering the leader state, the server device schedules one or more tasks by assigning each of the one or more tasks to a server device in the cluster.
