Abstract: Methods, systems, and computer programs encoded on computer storage media, for processing user-defined functions in containers. One example system receives a query written in a primary query language that calls a user-defined function. The system assigns primary segment hosts to process portions of the query written in the primary query language and assigns first containers to process the call to the user-defined function. The primary segment hosts provide to the first containers the user-defined function and one or more arguments in the call to the user-defined function. The first containers execute the user-defined function. The primary segment hosts receive an initial result of the call to the user-defined function computed by the first containers. The primary segment hosts compute a final result of the query using the initial result. The primary segment hosts provide the final result of the query in response to receiving the query.

Abstract: A computer-implemented method, medium, and system for global deadlock detection in a hybrid database for transactional and analytical workloads are disclosed. In one computer-implemented method, a daemon is launched on a coordinator segment in a massively parallel processing (MPP) database, where the MPP database is a hybrid database for both transactional workloads and analytical workloads. A respective local wait-for graph for each of a plurality of segments in the MPP database is collected periodically, where each of the plurality of segments includes the coordinator segment or a worker segment of a plurality of worker segments in the MPP database. A global wait-for graph that includes all collected local wait-for graphs is built. The global wait-for graph is used to determine that a global deadlock exists in the MPP database. The global deadlock is broken using one or more predefined policies in response to determining that the global deadlock exists.

Abstract: A method for relieving vaulted expansion of a cement-stabilized base layer through precut seams. The method firstly establishes an RBFN model according to a large number of observation results of a vaulted expansion amount of the cement-stabilized base layer under different conditions (such as temperature and a stress release structure) in Xinjiang and similar regions; and on such a basis, the vaulted expansion amount of the cement-stabilized base layer to be designed is predicted. When the vaulted expansion amount is greater than a control requirement, the RBFN model is configured to design a reasonable width and a reasonable interval of the precut wide expansion seams to ensure that the vaulted expansion amount of the cement-stabilized base layer is less than a control value. Based on the design of the RBFN model, the present invention provides a corresponding construction method for the precut wide expansion seams.

Abstract: A surfactant that changes the wettability of tight sandstone and its preparation method and application. By adding the aqueous phase solution into the oil phase solution, and under the action of the emulsifier, a uniformly dispersed phase is achieved. Then adding initiator, stirring and raising the temperature, reacting the reaction at the temperature to obtain a colorless and transparent liquid, i.e., high polymer. At room temperature, adding fluorocarbon surfactant and biosurfactant and stirring was continued for 4 hours to obtain a surfactant that changes the surface wettability of tight sandstone. The surfactant of the present invention can reduce the oil-water interfacial tension, transform the oil-wet surface into water-wet surface, which reduces the adhesion of oil droplets to rock surface and improves the flowability of crude oil in the original stratum, and improves the recovery of low-permeability reservoir.
