Abstract
System, method, and various embodiments for a query execution system with plan reuse are described herein. An embodiment operates by receiving a query on a database, the received query comprising one or more constants. Normalization is performed on the query, replacing the one or more constants with a variable-indicator. The normalized query is compared to one or more previously executed queries to identify a matching query. A matching execution plan corresponding to the matching query is selected. The matching execution plan is executed, for which the one or more constants are provided as runtime variables. A result from the execution of the matching execution plan is generated and returned.
