Abstract: Systems and methods are disclosed for receiving, at a data intake and query system, a query that includes an indication to process data managed by a third-party data storage and processing system that supports a different query language than the data intake and query system. The data intake and query system identifies a third-party data storage and processing system that manages the data to be processed and generates a subquery for execution by the third-party data storage and processing system, generates instructions for one or more worker nodes to receive and process results of the subquery from the third-party data storage and processing system, and instructs the worker nodes to provide results of the processing to the data intake and query system.

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: Disclosed is a technique that can be performed in a distributed computer network. The technique can include a worker node that receives search instructions defined by a search service based on at least a portion of a search scheme defined by a data intake and query system, to cause the worker node to obtain search results from distributed data storage systems communicatively coupled to the worker node over a network. The distributed data storage systems include an external data storage system and/or an internal data storage system of the data intake and query system. The worker node obtains the search results by searching the distributed data storage systems in accordance with the search instructions, and communicating, over the network to the search service, a combination of search results based on the search results to cause an output by the data intake and query system in accordance with the search scheme.

Abstract: Systems and methods are disclosed for processing and executing queries against one or more dataset. As part of processing the query, the system determines whether the query is susceptible to a significantly imbalanced partition. In the event, the query is susceptible to an imbalanced partition, the system monitors the query and determines whether to perform a multi-partitioning determination to avoid a significantly imbalanced partition.

Abstract: The disclosed embodiments also include monitoring and metering services of the data fabric service (DFS) system. Specifically, these services can include techniques for monitoring and metering metrics of the DFS system. The metrics are standards for measuring use or misuse of the DFS system. Examples of the metrics include data or components of the DFS system. For example, a metric can include data stored or communicated by the DFS system or components of the DFS system that are used or reserved for exclusive use by customers. The metrics can be measured with respect to time or computing resources (e.g., CPU utilization, memory usage) of the DFS system. For example, a DFS service can include metering the usage of particular worker nodes by a customer over a threshold period of time.

Abstract: Systems and methods are described for assigning a processing task from one component of a data intake and query system to a different component of the data intake and query system. As part of processing a query, the system can determine that a particular processing task is to be executed by a particular component of the data intake and query system. Based on the characteristics of the component that is to execute the processing task, the system can assign the task or a supplemental task to one or more other components of the data intake and query system.

Abstract: Systems and methods are disclosed for executing a query that includes an indication to process data managed by an external data system. The system identifies the external data system that manages the data to be processed and generates a subquery for the external data system. The system determines a data ingest estimate and uses the data ingest estimate to generate instructions for one or more worker nodes to receive and process results of the subquery from the external data system.

Abstract: Systems and methods are disclosed for executing a query that includes an indication to process data managed by an external data system. The system identifies the external data system that manages the data to be processed, and obtained search configuration data from the external system. The system uses the search configuration data to generate a subquery for the external data system. The system also generates instructions for one or more worker nodes to receive and process results of the subquery from the external data system.
