Abstract: A system, method, and computer readable medium for optimizing throughput of a stream processing system are disclosed. The method comprises analyzing a set of input streams and creating, based on the analyzing, an input profile for at least one input stream in the set of input streams. The input profile comprises at least a set of processing requirements associated with the input stream. The method also comprises generating a search space, based on an initial configuration, comprising a plurality of configurations associated with the input stream. A configuration in the plurality of configurations is identified that increases throughput more than the other configurations in the plurality of configurations based on at least one of the input profile and system resources.

Abstract: A system and method, which registers and stores data and is responsive to queries through management of an inferencing-enabled metadata includes an intelligent database, which receives data or queries and manages data models. An ontology management system is associated with the intelligent database and receives and stores classes of information related to a data model therein to be employed in satisfying queries. A relational database is associated with the intelligent database and receives and stores attribute schema for instances of the class having at least one attribute value linked with the class in the ontology management system.

Abstract: A system, method, and computer readable medium for reducing message flow on a message bus are disclosed. The method includes determining if at least one logical operator in a plurality of logical operators requires processing on a given physical processing node in a group of physical nodes. In response to determining that the logical operator requires processing on the given physical processing node, the logical operator is pinned to the given physical processing node. Each logical operator in the plurality of logical operators is assigned to an initial physical processing node in the group of physical processing nodes on a message bus.

Abstract: A mechanism for end-to-end mobile e-business applications for migration of business processes and business context between two or more clients and servers to provide transparency and reliability given unreliable networks and systems is disclosed. The e-business applications include mobile purchasing, retail point of sales, and inventory replenishment. The design of the novel mechanism takes into consideration migration of business processes and business context between clients and servers making the business activities transparent to the user of the mobile clients or networked clients.

Abstract: A computer-implemented method is provided for performing key lookups. The method comprises accessing a header of a given one of a plurality of nodes in a tree-based data index structure. The given node comprises the header and a plurality of partitions. Each partition comprises at least one key. The header of the given node comprises a selected key from each of a selected plurality of the partitions. The method also comprises choosing, using a search key, a selected key in the header. The method further comprises accessing a partition corresponding to the chosen selected key and selecting, using the search key, one of the at least one keys in the accessed partition. The selected one of the at least one keys can be used to access another of the plurality of nodes. Yet additional methods, apparatus, and program products are disclosed.

Abstract: A system, method, and computer readable medium for reducing message flow on a message bus are disclosed. The method includes determining if at least one logical operator in a plurality of logical operators requires processing on a given physical processing node in a group of physical nodes. The logical operator is pinned to the given physical processing node. The pinning prevents any subsequent reassignment of the logical operator to another physical processing node. Each logical operator in the plurality of logical operators is assigned to an initial physical processing node in the group of physical processing nodes on a message bus. A determination is made as to whether at least one logical operating in the plurality of logical operators needs to be reassigned to a different physical processing node. The at least one logical operator is reassigned to the different physical processing node.
