Abstract: A mechanism is disclosed for automatically detecting whether the client device is experiencing wireless communication issues and switching communications from a first server group to second server group, if necessary. Responsive to determining that the client device is experiencing wireless communication issues, the system performs a health check against the second server group, and responsive to determining, based on the health check, that the issue is on the client device, the system refrains from failing over to the second server group. Responsive to determining that the client device is not experiencing issues, the system fails over to a second server group. When the client device determines that the first server group is available, the client device fails back to the first server group.

Abstract: The disclosed embodiments provide a system for monitoring resource usage statistics. During operation, the system obtains a set of expiration times associated with usage of the resource. Next, the system selects a first limit to a number of time slots for use in calculating usage statistics for the resource based on a memory efficiency associated with calculating the usage statistics for the resource. The system then populates, up to the first limit, a set of time slots after a current time with the expiration times. When a time slot in the set of time slots includes the current time, the system uses a subset of the expiration times in the time slot to update one or more usage statistics for the resource. Finally, the system outputs the one or more usage statistics for use in managing the usage of the resource.

Abstract: Embodiments of the invention provide systems and methods for performing static analysis of query expressions embedded in programming language source code. According to one embodiment, performing static analysis of one or more query expressions embedded in programming language source code can comprise extracting the one or more query expressions from the programming language source code, performing the static analysis on the extracted one or more query expressions, and reporting results of performing the static analysis on the one or more query expressions, wherein the results relate errors and warning generated by performing the static analysis to the source code from which the one or more query expressions are extracted.
