Abstract: Systems and methods are disclosed for processing and executing queries in a data intake and query system. The data intake and query system receives 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 identifies buckets that are to be searched. The data intake and query system performs a hash on bucket identifiers of the identified buckets to identify search nodes to search the buckets.

Abstract: 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.

Abstract: Systems and methods are disclosed for processing and executing queries in a data intake and query system. The query identifies a set of data to be processed and a manner of processing the set of data. The data intake and query system dynamically identifies a plurality of containerized search nodes instantiated on one or more computing devices in a containerized environment to execute the query. The data intake and query system executes the query using the containerized search nodes.

Abstract: The disclosed embodiments include a method performed by a data intake and query system. The method includes receiving a search query by a search head, defining a search process for applying the search query to indexers, delegating a first portion of the search process to indexers and a second portion of the search process to intermediary node(s) communicatively coupled to the search head and the indexers. The first portion can define a search scope for obtaining partial search results of the indexers and the second portion can define operations for combining the partial search results by the intermediary node(s) to produce a combination of the partial search results. The search head then receives the combination of the partial search results, and outputs final search results for the search query, where the final search results are based on the combination of the partial search results.
