Abstract: Disclosed herein are system, method, and computer program product embodiments for updating metadata associated with a data model. The data model comprises entities arranged into a plurality of entity groups. A determination is made that the data model has been changed based on either a first or second trigger event. If the determination is based on the first trigger event, the entities in the plurality of entity groups are resolved, and for the entities that resolved successfully, updated metadata is generated commensurate with the change and subsequently saved. If the determination is based on the second trigger event, a first entity group of the plurality of entity groups that is associated with the change is determined. All entities in the first entity group are resolved, and for the entities in the first entity group that resolved successfully, updated metadata commensurate with the change may be generated and subsequently saved.

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.

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 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: System computing resources are dynamically managed by a resource management layer together with resource server pool. A group monitor collects data of server operation (e.g., CPU usage, memory consumption, queue size) in a particular group (e.g., customer-facing servers, job servers). The group monitor: calculates a weighted score for each server, sorts the scores of each server, maintains a sequence of scores, and periodically reports the score list to a resource manager. When an incoming request is directed to a particular server group, the group monitor redirects the request to a lowest-scoring server, and recalculates/sorts the score list. The resource manager monitors and throttles the servers in each group. Where servers in a group are experiencing high workload, the manager adds to the group server(s) from the resource pool. Conversely, where server group members are experiencing a low workload, the manager removes the lowest scoring server(s) to the resource pool.

Abstract: A cloud computing system receives a plurality of requests originating from a plurality of tenants. Thereafter, a load balancer forming part of the cloud computing system dispatches each request to one of a plurality of groups of servers based on a group mapping table configured to optimize a cache hit ratio. Each group of servers includes a plurality of servers dispatching each request to one of the plurality of servers within each group of servers. The cloud computing system provides responses to the requests to the respective tenants as generated by the respective servers within the respective groups of servers. The group mapping table can be generated by monitoring historical request statistics for each of the tenants, monitoring current resource consumption by the plurality of groups of servers when handling requests from the tenants, and associating each tenant with one of the groups of servers based on such monitoring.

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.
