Publication number: 20180096029Abstract: The present disclosure relates to a computer-implemented method, computer program product, and computer system, for optimization of query processing a set of data extents on which a table is stored. Attribute value information may be maintained for each data extent. The attribute value information indicate as ranges the minimum and maximum values of an attribute of the entries stored in the respective extent. A first metric of a first data extent of the set may determine splitting the first data extent into sub-extents increases query processing efficiency. A second metric of a second data extent and a third data extent may determine merging the second data extent and the third data extent increases query processing efficiency.Type: ApplicationFiled: December 6, 2017Publication date: April 5, 2018Inventors: Michal Bodziony, Andreas Brodt, Lukasz Gaza, Artur M.

Patent number: 9922083Abstract: A computer-implemented method for partitioning data for a query operation of one table of the database system is provided. The computer-implemented method comprises estimating a value distribution of the attribute in the result table based on a first value distribution of the attribute in the first column of the first table. The computer-implemented method further comprises determining boundaries for partitioning ranges of the attribute, based on the estimated value distribution, wherein the partitioning ranges correspond to a same number of rows of the result table. The computer-implemented method further comprises partitioning the first table with processing nodes of the query operation, based on the determined boundaries of partitioning ranges.Type: GrantFiled: June 5, 2015Date of Patent: March 20, 2018Assignee: International Business Machines CorporationInventors: Lukasz Gaza, Artur M.

Patent number: 9778973Abstract: A method, system and computer program product for providing early diagnosis of hardware, software or configuration problems in a data warehouse system. A received query is parsed to determine the properties of the query. The query may then be joined to existing groups of queries if those groups have shared properties of the query. After executing the query according to an execution plan, results from the execution of the query is received, which may include problem(s) that occurred during execution of the query. For those problems that reach a pre-defined threshold of becoming a “group problem” in those groups joined by the query, the problem is reported to the end user concerning those groups where the problem exceeds the pre-defined threshold. In this manner, an early diagnosis of the problems in the data warehouse system that can cause delay and failure of the processing of queries is able to occur.Type: GrantFiled: October 28, 2015Date of Patent: October 3, 2017Assignee: International Business Machines CorporationInventors: Lukasz Gaza, Artur M.

Publication number: 20170180223Abstract: A method for determining when to send monitoring data to a server within a monitoring infrastructure. The method includes a first agent computer collecting a first instance of monitoring data relating to an alert on a computer system, wherein the collecting is based, at least in part, on a set of instructions received from a monitoring server, wherein the set of instructions includes instructions for determining whether the monitoring data is relevant to triggering the alert. The first agent then receives at least one second instance of monitoring data from a set of second agents. The first agent then determines whether the first instance of monitoring data is relevant to triggering the alert based, at least in part, on the first instance of monitoring data and the second instance of monitoring data. The first agent then determines whether to send the first instance of monitoring data to the monitoring server.Type: ApplicationFiled: March 9, 2017Publication date: June 22, 2017Inventors: MICHAL BODZIONY, LUKASZ GAZA, ARTUR M.

Publication number: 20170147640Abstract: In an approach to preparing a query execution plan, a host node receives a query implicating one or more data tables. The host node broadcasts one or more implicated data tables to one or more processing nodes. The host node receives a set of node-specific query execution plans and execution cost estimates associated with each of the node-specific query execution plans, which have been prepared in parallel based on global statistics and node-specific low level statistics. The host node selects an optimal query execution plan based on minimized execution cost.Type: ApplicationFiled: November 23, 2015Publication date: May 25, 2017Inventors: Lukasz Gaza, Artur M.
