Abstract: Methods, systems, and computer program products for processing a query to determine query results. The query may be analyzed to determine a constant column pair corresponding to the query. The column constant pair may be analyzed with respect to a column constant pair associated with a partitioned data set in order to route the query to a subset of the data set. Data sets may be partitioned into subsets by analyzing historical queries to determine a partitioning column constant pair with respect to the data set that is used to partition the data of the data set into subsets. The query processing may include both query routing and data set partitioning.

Abstract: An example method of loading data from a database includes receiving, at a cache node, a current query and a data chain that includes a sequence of ordered queries. The method also includes determining whether a hash of the current query matches a hash of an expected query in the data chain. The method further includes retrieving a result set of the current query from a local cache in response to determining that the hash of the current query matches the hash of the expected query. The method also includes sending the result set of the current query to a client.

Abstract: An example method for processing a batch job that includes a plurality of sequentially ordered tasks includes obtaining a message that includes inputs of a plurality of tasks included in a batch job. The plurality of tasks includes a first task that is sequentially ordered before a second task. The method also includes assigning tasks of the plurality of tasks to different computing nodes. The first task is assigned to a first computing node associated with a first public key, and the second task is assigned to a second computing node associated with a second public key.

Abstract: A processing device receives a request from a client for a specific service. Responsive to determining that the specific service is not running, the processing device converts a previously instantiated generic service into the specific service. To perform the conversion, the processing device assigns the generic service from a service pool for the specific service and renames the generic service based on a name of the specific service. The processing device additionally queries a directory service for specific service logic associated with the specific service. The processing device receives at least one of the specific service logic or a reference to the specific service logic from the directory service, and updates the generic service to include at least one of the specific service logic or the reference to the specific service logic.

Abstract: An example method for controlling access to services coupled to an application server includes receiving a set of method calls issued from originator services to target services and recording information about the set of method calls into a data structure. The method also includes modifying, based on user input, the data structure to exclude each unauthorized method call from the data structure. The method further includes receiving a first method call from a first originator service to a target service, and determining, based on searching the data structure, whether the first originator service is authorized to issue the first method call to the first target service. In response to a determination that the first originator service is not authorized to issue the first method call to the first target service, the application server may block the first originator service from issuing the first method call to the first target service.

Abstract: An example method of submitting a federated query to one or more data sources belonging to a federation includes splitting a zone into a plurality of zone subsets. The zone includes a plurality of data sources belonging to a federation. The plurality of zone subsets has disjoint sets of data sources belonging to the federation. The method also includes receiving a federated query from a client. The federated query includes a plurality of source queries. Each source query of the plurality of source queries is specific to an autonomous data source belonging to the federation. The method further includes determining the client's assigned zone subset of the plurality of zone subsets. The method also includes submitting the federated query to the client's assigned zone subset. The plurality of source queries is submitted to one or more data sources in the zone subset to which the client is assigned.

Abstract: Providing messages for Java message service (JMS) is disclosed. A described method includes determining timestamp information associated with a first Java™ message service (JMS) message. The timestamp information represents a time when the JMS message is either generated or received by a processing device. The method also includes determining destination information associated with the JMS message. The method further includes converting the JMS message into a first key-value data pair having a key data and a value data. The key data includes the timestamp information and the value data includes the destination information of the first JMS message.
