Abstract: According to some embodiments, methods and systems may provide request governance in a multi-tenancy cloud computing environment of an enterprise. A default cluster and a quarantine cluster may each execute application servers, and an automated quarantine enterprise configuration may store automatically managed tenant identifiers. An automated quarantine manager may automatically determine which tenant identifiers are stored in the automated quarantine enterprise configuration (e.g., based on a dynamic sliding time window). The automated quarantine manager may receive a tenant request from a client and arrange for the received tenant request to be executed by an application server in either the default cluster or the quarantine cluster in accordance with an associated tenant identifier in the automated quarantine enterprise configuration.

Abstract: A computer-implemented method can receive a software update for a software application deployable on a target system and perform an automatic performance test of the software application incorporating the software update on the target system. The automatic performance test can be integrated in a continuous integration and continuous delivery (CI/CD) pipeline. The method can collect a plurality of performance metrics measured when performing the automatic performance test and determine a performance score based on the plurality of performance metrics. Responsive to detecting the performance score is below a predefined performance threshold, the method can cause the CI/CD pipeline to reject the software update to the software application.

Abstract: Disclosed herein are system, method, and computer program product embodiments for processing a data query from a user device. In an embodiment, a data storage operator receives the data query from the user device. The data storage operator determines that the data query is a snapshot query and the snapshot query does not have a skiptoken. The data storage operator then determines that the snapshot query satisfies snapshot conditions and takes a snapshot based on the snapshot query. The data storage operator stores the snapshot into the snapshot storage and extracts data from a data storage based on the snapshot. The disclosed system enables an intelligent data query by determining whether or not to perform snapshot query. When performing snapshot query, the snapshot is stored in the snapshot storage for future use. In such a case, the data query is efficient and accurate.

Abstract: In an example embodiment, to improve performance, a solution is provided that removes the bottleneck associated with a single events table. Specifically, the solution provides for three events tables rather than one table. Two of the three tables are domain event outbox tables that are parallel and equivalent to each other. The third table is a domain event indication table, which records which of the domain event outbox tables is in a serve mode versus a maintain mode. At any point in time, one of the two domain event outbox tables is in serve mode while the other is in maintain mode. Serve mode is used for event insert, update, and query, while maintain mode is used for event purge.

The one or more configuration values are received from the plurality of configuration agents at the collection system. The one or more configuration values are stored in one or more databases, organized based on one or more server identifiers.

Abstract: Methods, systems, and computer-readable storage media for adaptive application server request balancing. An example method includes receiving, from a load balancer, an application request for a first application at a first application server. In response to determining that a complexity value for the application request is greater than a complexity value threshold and that an occupancy value for the first application server is greater than an occupancy value threshold, the application request is provided to a global task queue that is accessible by the first application server and other application servers. A notification is received from a second application server of a completion of the application request by the second application server. A completion result of the completion of the application request by the second application server is retrieved from a global results queue and the completion result is provided to the first application in response to the application request.

Abstract: A log sampling and storage system reduces volumes of stored log information. A log storage engine receives a series of log messages responsive to a request. The engine compares that series to various patterns previously generated from historical log data. This comparison can reference •a name of the request; •a total time to process the request; •an item count; •a message length; and/or •a message hash code. Comparing incoming log series with the predefined patterns, results in generation of a similarity score. If the score falls outside a tolerance, the existence of an outlier log message series is indicated, and that outlier log message series is stored in its entirety. However, if the similarity score falls within a tolerance, similarity to an existing predefined pattern is indicated. Rather than storing the (non-outlier) log message series, the engine directs storing a link to a sample log message series reflecting the pattern.

Abstract: A flexible radar support for absorbing vibration deviation comprises a support base and a support top cover that are engaged with each other in an interlocking manner. A housing space for arranging a radar is formed between the support base and the support top cover. The support base includes: a centrally arranged base center, and a base edge circumferentially arranged around the base center. The base edge and the base center are connected through four flexible structures that form U-shaped cantilever beams protruding towards the support top cover. With the flexible radar support provided, and with the design of U-shaped flexible structures, where an automobile body vibrates at a large amplitude, the flexible radar support can still absorb swaying in the up and down, and left and right directions during the course of driving, thereby reducing the impact of the automobile body's vibrations on the detection precision of a radar.
