    摘要： A method, computer program product, and a system where a processor(s) intercepts a query from a client targeting a database. The processor(s) analyzes the query to determine contextual data relevant to the query and determines, based on a data masking policy, if a portion of results responsive to the intercepted query should be provided to the client as masked data. When the processor(s) determines that the portion of the results should be provided to the client as masked data, the processor(s) determines computing resources managing data comprising the results responsive to the intercepted query. The processor(s) executes the query on the computing resources by obtaining the masked data via coprocessors deployed on the computing resources, where the coprocessors mask the portion of the results. The processor(s) returns query results comprising the portion of the results masked by the coprocessors, to the client.

    摘要： Aspects of the present invention disclose a method for ordering rows of a table based on access statistics. The method includes one or more processors adding a respective tracking mechanism to the attribute of each respective instance of the set of rows of the table of the database. The method further includes adding a tracking mechanism to the respective instances of the set of rows. The method further includes gathering access data of the respective tracking mechanism of the attribute of each respective instance of the set of rows. The method further includes determining each respective instance of an attribute value that corresponds to the access data of the respective tracking mechanism of each respective instance of the set of rows. The method further includes ordering each respective instance of the set of rows of the table based at least in part on the respective instances of the attribute values.

    摘要： Optimization of job execution includes generating a hash tree for an initial dataset, executing a data processing job against the initial dataset, the job including a set of calculations against data of the records of the initial dataset, generating, based on a modification to the initial dataset to produce a modified dataset, a hash tree for the modified dataset, comparing the hash tree for the initial dataset to the hash tree for the modified dataset, and identifying one or more blocks of the modified dataset that are updated compared to the initial dataset, and re-executing the job against the modified dataset. The re-executing performs only those calculations that use data of the records of the one or more blocks that are updated compared to the initial dataset, and does not perform other calculations that do not use data of the records of the one or more blocks.
