Abstract: A system and method of caching and parameterizing intermediate representation code includes receiving, by a database, a query, parsing, by the database, the query to obtain a plan tree comprising a plurality of plan nodes arranged in hierarchical order descending from a top plan node, generating, by the database, node intermediate representations (IRs) for the plan nodes, executing, by the database, a first query using the node IRs, and reusing, by the database, the node IRs to execute subsequent queries.
