Abstract: Systems and methods are disclosed for processing streaming data. The data can come from various sources. Worker nodes can be configured to process the streaming data, without delays that may be caused by indexing the data. The data can be filtered and/or transformed as it is processed. In some cases, data can be stored in a data store without transformation. The data in the data store can be accessed and processed at a later time.

Abstract: Systems and methods are disclosed for receiving and executing a query received from a data intake and query system and providing results to a first group of worker nodes in a distributed execution environment. The query identifies a set of data to be processed and a manner of processing the set of data. Based on the query, the system defines a query processing scheme, and generates instructions for a second group of worker nodes to obtain the set of data from one or more dataset sources and to process the set of data. The system communicates results of the query to the first group of worker nodes.

Abstract: Systems and methods are described for processing data by interactions with a publish-subscribe messaging system. The processing may include receiving messages published to at least one publish-subscribe messaging system, the messages containing data collected during operation of one or more source computing systems and iteratively processing the received messages through the publish-subscribe messaging system, wherein iteratively processing a message comprises serially republishing the message to the at least one publish-subscribe messaging system and altering the message between individual republishings according to a set of rules, and wherein a final republishing of the message during the serial republishing makes a version of the message available on the at least one publish-subscribe messaging system to a downstream component.

Abstract: Systems and methods are disclosed for processing and executing queries in a data intake and query system. An indexing system of the data intake and query system receives data from an ingestion buffer that includes a marker that indicates data that is made available to the indexing system. The data intake and query system stores at least a portion of the data in buckets and stores the buckets in a shared storage system. Based on the storage of the buckets in the shared storage system, the indexing system indicates to the ingestion buffer that the marker can be updated.

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: Disclosed is a technique that can be performed in a distributed network. The technique can include a search service system that receives an indication of at least a portion of a search scheme to cause worker nodes to obtain search results from distributed data storage systems. The search scheme is defined by a data intake and query system. The search service system defines a search process based on the at least a portion of the search scheme and executes the search process to cause the worker nodes to obtain search results from the distributed data storage systems. The search service system receives a combination of search results based on the search results obtained by the worker nodes from the distributed data storage systems, and causes an output based on the combination of search results obtained by the data intake and query system in accordance with the search scheme.

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 uses a search node catalog to identify search nodes that are available to execute the query and uses a bucket catalog to identify buckets to be searched. The data intake and query system executes the query using the identified bucket and search nodes.

Abstract: Systems and methods are disclosed for processing and executing queries in a data intake and query system. The data intake and query system maintains a catalog of buckets stored in a remote shared storage system. The buckets store raw machine data associated with a timestamp. The data intake and query receives a query identifying a set of data to be processed and a manner of processing the set of data, and executes the query based on the catalog of buckets.

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 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 uses one or more containerized search nodes to execute the query and stores the results in a data store for combination with additional query results.
