Method and Plan Optimizing Apparatus for Optimizing Query Execution Plan

摘要

A method for optimizing query execution comprises receiving one or more optimizing parameters from a user device for optimizing a query execution plan. The one or more optimizing parameters comprise at least one of a query statement, a planning time and a plan execution time. The one or more optimizing parameters are received when duration of execution of the one or more queries using the query execution plan is greater than a predefined time period required for executing the one or more queries. The query execution plan is latest of one or more query execution plans for executing one or more queries. The method comprises generating an optimized query execution plan by iterating optimization of the query execution plan until the optimization satisfies the one or more optimizing parameters.
