Abstract
The subject technology receives a query. The subject technology performs a lookup operation on a shadow cache. The subject technology performs a validation process on the particular query plan for determining a cache hit on the shadow cache. The subject technology performs a program building process to update the particular query plan with additional information for executing the particular query plan. The subject technology performs a compilation process to compile an updated program of the updated particular query plan. The subject technology determines that the updated particular query plan is cacheable based at least in part on the compilation process. The subject technology registers the updated particular query plan as a new entry in the shadow cache. The subject technology sends the updated program to an execution node for executing the updated particular query plan.
