Abstract
A method for intelligent query plan cache size management can be implemented. The method measures actual compilation times of generating query execution plans for a plurality of incoming queries. At least some of the query execution plans are stored in a query execution plan cache. The method can estimate ideal compilation times of generating the query execution plans for the plurality of incoming queries under an assumption that no query execution plan is evicted from the query execution plan cache, monitor differences between the actual compilation times and the ideal compilation times in continuous time windows, and adjust a size of the query execution plan cache in runtime based on the monitored differences.
