System, method, and computer program product to perform an operation, comprising receiving job information for a stream computing application, the job information comprising a plurality of processing elements configured to process streaming data tuples according to an execution path defined by a operator graph, deploying a first set of processing elements of the plurality of processing elements to one or more compute nodes, initializing a subset of the first set of processing elements, executing the stream computing application on the first set of processing elements, and, responsive to receiving a predefined number of data tuples to be processed by an additional processing element of the plurality of processing elements when executing the stream computing application, deploying the additional processing element to the one or more compute nodes, and initializing the additional processing element.

Lazy initialization of operator graph in a stream computing application

A system, method and article of manufacture for identifying mergeable data in a data processing system and, more particularly, for identifying correlated columns from one or more database tables. One embodiment comprises determining correlation attributes for a first column and a second column from one or more database tables. The correlation attributes describe for each column at least one of the column and content of the column. The correlation attributes from the first and second column are compared and similarities between the first and second column are identified on the basis of the comparison. Then, on the basis of the identified similarities, it is determined whether the first and second columns are correlated. Only if the columns are determined to be correlated, the first and second columns are merged.

Techniques for identifying mergeable data

The present invention provides for methods directed to dynamically generating input to an analysis environment. Varying input data is linked with analysis routines by provision of a well defined but general purpose input structure for selected data, which is used as input to analysis routines. Metadata is used to describe the multiple analysis routines and their capabilities, and a framework both automatically formats the input data and customizes the analysis routine to accept the specific dynamic fields available in the input. In this manner, data (e.g., a query) containing new input fields is dynamically made available to multiple existing analysis techniques.

Framework for dynamic analysis of varying structured data using multiple analysis techniques

A system, method and article of manufacture for identification of mergeable data in a data processing system and, more particularly, for providing mechanisms for facilitating identification of correlated columns from one or more database tables. One embodiment provides a computer-implemented method for managing storage of data having an associated measurement unit in a database table. The method includes storing the data in a column of the database table and generating units metadata describing the measurement unit. The units metadata is associated with the column of the database table.

Method, system and article of manufacturing for converting data values quantified using a first measurement unit into equivalent data values when quantified using a second measurement unit in order to receive query results including data values measured using at least one of the first and second measurement units
