摘要： Systems and methods are disclosed for mapping search nodes to a search head in a data intake and query system based on a tenant identifier in order to execute a query received by the data intake and query system. The mapping may allow same or similar search nodes to be used to execute queries that are associated with a particular tenant identifier, in order to take advantage of caching and local data stored with those search nodes. In some cases, search nodes can be mapped based on the tenant identifier using a hashing algorithm, such as a consistent hashing algorithm.

摘要： Systems and methods are disclosed for dynamically assigning a search head or search nodes in a data intake and query system for a query received by the data intake and query system. Existing search heads and search nodes can periodically report their status to the data intake and query system, which can use that information to help determine the need to provision additional search heads and search nodes. The data intake and query system can receive a query identifying a set of data to be processed and a manner of processing the set of data. The data intake and query system can use the status information for existing search heads and search nodes to dynamically assign a search head and search nodes for the query. Dynamically assigning the search head and search nodes in this manner may provide many benefits, including improved load balancing and resource utilization.
