Abstract: Systems and methods are described for a implementing a streaming data processing system that includes a pool of pre-configured resources and a pool of dedicated resources. The streaming data processing system can implement a processing pipeline using compute resources. The pool of pre-configured resources can support previews of processing pipelines for a plurality of users and the pool of dedicated resources can support full deployments of processing pipelines for a particular user. The streaming data processing system can implement a preview of a processing pipeline using a pre-configured resource of the pool of pre-configured resources. Further, the streaming data processing system can implement the processing pipeline using a dedicated resource of the pool of dedicated resources. The streaming data processing system can provision the dedicated resource and deploy the processing pipeline using the dedicated resource.

Abstract: Systems and methods are described for providing previews of deployment of data stream processing instructions sets, sometimes called pipelines, to a stream data processing system. Rather than deploying such an instruction set, which may cause detrimental side effects, previews can be facilitated by conversion of a data stream processing instructions set to a batch query that is applied to an existing data set. An output of the batch query can then be provided to an end user as a preview of output of the data stream processing instructions set, when implemented.

Abstract: Systems and methods are described for performing dynamic data enrichment in accordance with data streaming. In this regard, dynamic data enrichment can be performed to process data later ingested into an indexing system. In performing dynamic data enrichment, a message can be obtained via a data stream. The message is analyzed to identify a data portion within the message to add to a lookup table. Thereafter, the data portion is written to the lookup table to enhance the lookup table with data from the message. The enhanced lookup table can then be used to lookup a data value to append to the message to enrich the message, and the enriched message can be output (e.g., to an indexing system).

Abstract: A liquid-cooled aperture body in an x-ray tube. In one example embodiment, an x-ray tube is configured to be at least partially submerged in a liquid coolant. The x-ray tube includes a cathode at least partially positioned within a cathode housing, an anode at least partially positioned within a can, and an aperture body coupling the cathode housing to the can. The can is formed from a first material and the aperture body is formed from a second material. The aperture body defines an aperture through which electrons may pass between the cathode and the anode. The aperture body further defines at least two exterior surfaces that are each configured to be exposed to the liquid coolant in which the x-ray tube is at least partially submerged.
