Abstract
Disclosed aspects relate to data arrangement management in a distributed data cluster environment of a shared pool of configurable computing resources. In the distributed data cluster environment, a set of data is monitored for a data redistribution candidate trigger. The data redistribution candidate trigger is detected with respect to the set of data. Based on the data redistribution candidate trigger, the set of data is analyzed with respect to a candidate data redistribution action. Using the candidate data redistribution action, a new data arrangement associated with the set of data is determined. Accordingly, the new data arrangement is established.
Claims20
A computer system for data arrangement management in a distributed data cluster environment of a shared pool of configurable computing resources, the computer system comprising:
- one or more computer processors, one or more computer-readable storage media, and program instructions stored on the one or more computer-readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising:
- program instruction to monitor, in the distributed data cluster environment, a set of data for a data redistribution candidate trigger;
- program instruction to detect, in the distributed data cluster environment, the data redistribution candidate trigger with respect to the set of data, wherein detecting the data redistribution candidate trigger comprises:
- program instruction to detect a data structure which indicates a workload pattern;
- program instruction to build a new distribution key for the data structure to change the workload pattern to reduce data movement during a query operation;
- program instruction to determine, based on the new distribution key, a new data arrangement associated with the set of data, and comparing the new data arrangement with a current data arrangement to determine which data arrangement is more efficient based on resource usage;
- and
- in response to determining that the new data arrangement is more efficient than the current data arrangement, program instruction to establish, based on the new distribution key, the new data arrangement in the distributed data cluster environment such that at least a portion of the set of data comprises a different physical location in the new data arrangement.
A computer system for data arrangement management in a distributed data cluster environment of a shared pool of configurable computing resources, the computer system comprising:
- one or more computer processors, one or more computer-readable storage media, and program instructions stored on the one or more computer-readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising:
- program instruction to detect, in the distributed data cluster environment, a data redistribution candidate trigger with respect to a set of data, wherein detecting the data redistribution candidate trigger comprises:
- program instruction to detect a data skew of a data structure which exceeds a threshold data skew value, the data skew being a disproportionate distribution of the set of data across multiple partitions of the distributed data cluster environment;
- program instruction to build a new distribution key for the data structure which exceeds the threshold data skew value to reduce the data skew of the data structure;
- program instruction to determine, based on the new distribution key, a new data arrangement associated with the set of data, and comparing the new data arrangement with a current data arrangement to determine which data arrangement is more efficient based on resource usage;
- and
- in response to determining that the new data arrangement is more efficient than the current data arrangement, program instruction to establish, based on the new distribution key, the new data arrangement in the distributed data cluster environment such that at least a portion of the set of data comprises a different physical location in the new data arrangement.
A computer system for data arrangement management in a distributed data cluster environment of a shared pool of configurable computing resources, the computer system comprising:
- one or more computer processors, one or more computer-readable storage media, and program instructions stored on the one or more computer-readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising:
- program instruction to detect, in the distributed data cluster environment, a data redistribution candidate trigger with respect to a set of data, wherein detecting the data redistribution candidate trigger comprises:
- program instruction to detect a data structure which exceeds a data transmission frequency threshold by detecting data structures using network bandwidth beyond a threshold amount during a particular temporal period;
- and
- program instruction to establish, in the distributed data cluster environment, a new data arrangement by deploying the data structure which exceeds the data transmission frequency threshold to at least a threshold number of partitions in the distributed data cluster environment to reduce overall computing resources utilization such that at least a portion of the set of data comprises a different physical location in the new data arrangement.
