| 20160378634 | AUTOMATED VALIDATION OF DATABASE INDEX CREATION - Automated validation of the creation of indices in an environment that include multiple and potential many databases, such as perhaps a cloud computing environment. A validation module validates index impact of a created index by using a validation data store that contains validation data originating from a database collection. Index impact may be estimated by evaluating validation data generated prior to and after the creation of the index to thereby determine whether the created index results in overall improved query performance on the database collection for those queries that target the newly indexed database entity. Such validation data need not even contain private data that was contained within the query itself, and might be, for instance, query performance data, or execution plans associated with the query, with private data redacted. | 12-29-2016 |
