Abstract: An example method of processing a query at a plurality of storage devices includes receiving a dual query from a client and generating a synchronous query and an asynchronous query based on the dual query. The dual query includes a set of conditions for selecting data from a set of database tables. The method further includes sending the synchronous query to a first storage device, sending the asynchronous query to a second storage device, and receiving a result set of the synchronous query. The result set of the synchronous query includes data selected from a set of database records in a set of primary database tables, which is stored in the first storage device and is a subset of the set of database tables. The method further includes marking a database record. A marked database record indicates usage of the data selected from the database record within a time period.

Abstract: An example method for processing a federated query includes determining, at a data federation tool, a source query embedded in a federated query. The source query includes a name of a table and one or more conditions for selecting data from the table. The method also includes sending, at the data federation tool, a request to compile a software package in accordance with a view description of the table to a data slave. The software package includes a set of source files and is associated with the table. The method further includes sending the source query to the data slave and receiving, at the data federation tool, the result of the source query from the data slave.

Abstract: An example system for processing a federated query includes a query proxy that receives a federated query including a plurality of source queries and receives an indication that a failed set of one or more source queries failed to execute successfully. Each source query is specific to an autonomous data source belonging to a federation. The system also includes a data federation engine that identifies a plurality of autonomous data sources to which to send the plurality of source queries. The plurality of autonomous data sources belong to the federation. The system further includes a query fail analyzer that updates a data structure to reflect the unsuccessful execution of one or more source queries of the failed set.

Abstract: Systems and methods for testing and deploying an update are provided. A first server can execute a current version of an application in a production environment. A client communication from a client to the first server can be identified. The client communication can be transmitted to a second server in the production environment. The second server can be executing an updated version of the application. A first response to the client communication from the first server and a second response to the client communication from the second server can be received. The first response from the first server can be compared with the second response from the second server to determine whether the updated version of the application is compatible with the production environment.

Abstract: A system and method of flexible holding storage during messaging includes determining one or more properties of a message, the message to be stored in a holding storage area of a messaging system, determining status of one or more candidate holding storage devices, determining one or more storage selection rules, adjusting the one or more storage selection rules based on information associated with the status of the one or more candidate holding storage devices, and selecting a holding storage device for the message from the candidate holding storage devices based on the adjusted storage selection rules and information associated with the properties of the message. The one or more storage selection rules express preferences among the one or more candidate holding storage devices. In some examples, the system and method further include sending the message to the selected holding storage device.

Abstract: Methods, systems, and computer program products are included for integrating software components. Source code corresponding to the software components is parsed to identify method calls. Method contracts, which contain identifying information corresponding to the method calls, are determined. The method contracts are used to query a dependency data store to identify dependencies that correspond to the method calls. Dependencies that are determined for a component are compared with dependencies for another component in order to identify dependencies that may be used to build the components together, and also to identify conflicting dependencies.

Abstract: An example method for reducing data communications includes receiving, at a data hub, a first set of messages from a first device. Each message of the first set includes a value. The method also includes sending one or more messages of the first set to one or more devices. The method further includes receiving a second set of messages from a second device. Each message of the second set indicates whether a state change occurred in the second device for one or more values included in the first set. The method also includes computing a value interval based on the one or more values associated with the first set. Values within the value interval were indicated in the second set as causing a state change in the second device. The method further includes configuring the first device to transmit messages for values within the value interval.

Abstract: Systems and methods are disclosed for processing messages using a dynamic messaging bus. An example system includes a plurality of services residing in a dynamic messaging bus including a plurality of sub-buses. Each service is assigned to a sub-bus of the plurality of sub-buses. The example system also includes a performance monitoring module that monitors a performance of one or more services executing on a sub-bus to which the respective one or more services is assigned. A first service is assigned to a first sub-bus and a second service is assigned to a second sub-bus. The example system further includes a swapping module that determines, based on the monitored performances of the first and second services, whether to swap the assignments of the first and second services such that the first service is assigned to the second sub-bus and the second service is assigned to the first sub-bus.
