摘要： A method, system, and program product for optimizing distribution and availability of data partitions is disclosed. Placement logic is run for data partition distribution which optimizes a configuration of a memory data grid. A determination of a change in performance of the memory data grid after adding new members to the memory data grid is provided. Replication of data partitions in the memory data grid is minimized. Optimum data partition distribution in the memory data grid is determined.

摘要： A code reuse user interface executed by a processor allows a code developer to specify unused data variables of a coded object definition to be reused, from pre-existing code within a new application, as a partial object without instantiation of the unused data variables. An indication from the code developer that at least one data variable of the reused coded object definition is specified as unused in the new application is detected within the code reuse user interface. The specified at least one unused data variable of the reused coded object definition is externalized from the code reuse user interface to a runtime environment, where as part of execution of the new application in the runtime environment, the runtime environment instantiates the reused coded object definition as the partial object without instantiation of the specified at least one unused data variable.

摘要： Embodiments of the invention provide a method, system and computer program product for data duplication detection in an in memory data grid (IMDG). A method for data duplication detection in an IMDG includes computing a hash value for each binary data value in a key value pair of a partition in an IMDG. The method also includes generating a map including an entry for each unique computed hash value and one or more keys corresponding to binary data values of respective key value pairs from which the hash value had been uniquely computed. Thereafter, only those hash values in the map with multiple keys associated therewith are identified and binary data corresponding to the multiple keys of the identified hash values are reported as potential duplicate data in the IMDG.

The method may include identifying at least two data object instances associated with the data set based on a determined relationship between the at least two data object instances. The method may also include performing a field relation analysis on the identified at least two data object instances and recording the field relation analysis. The method may include receiving a request for a data object associated with the data set. The method may include determining if an optimization can be performed on the data object. The method may include omitting a field value associated with the data object based on the determined optimization. The method may include inflating the omitted field value into the data set associated with the data object request and returning the data set with the inflated field value.

摘要： Embodiments of the present invention disclose a method, computer program product, and system for optimizing objects in object oriented programming. A computer receives application code having a plurality of application object fields. The computer receives information detailing a set of user-defined classes, wherein the user-defined classes include at least one object field. The computer analyzes the plurality of application object fields and the information detailing the set of user-defined classes to identify at least one object field in the set of user-defined classes that does not appear in the plurality of application object fields. The computer generates an instance of at least one user-defined class of the set of user-defined classes, wherein the instance does not include the at least one object field that does not appear in the plurality of application object fields.

摘要： Various embodiments include solutions for querying desired data from a database without pulling supererogatory data. In one embodiment, a method includes: obtaining an initial database access query between an application and the database at a self-learning JDBC driver; monitoring subsequent database access queries between the application and the database over a period; and generating a modified database access query for querying the database from the self-learning JDBC driver, the modified database access query based upon the subsequent database access queries between the application and the database over the period.

摘要： A method, system and computer program product for autonomic caching in an IMDG has been provided. A method for autonomic caching in an IMDG includes receiving from a client of the IMDG a request for a primary query in the IMDG. The method also includes associating the primary query with a previously requested sub-query related to the primary query. Finally, the method includes directing the sub-query concurrently with a directing of the primary query without waiting to receive a request for the sub-query from the client. In this way, the method can proactively predict a receipt of the request for a sub-query following a request for a primary query prior the actual receipt of the request for the sub-query.
