Abstract
A hybrid transactional/analytical processing database includes an OLTP engine, OLAP engine, and shared storage including a mass storage device holding data of multiple tenants. The shared storage includes processing circuitry configured to implement a query executor configured to continuously monitor actual memory usage of the shared storage while the shared storage is responding to one or more queries from the OLTP engine or OLAP engine. Upon determining the actual memory usage of an operator evaluating the one or more of the queries from the OLTP engine or OLAP engine at the shared storage exceeds the preventative memory usage threshold but does not exceed the system memory usage threshold, the query executor is further configured to spill one or more fragments of query memory corresponding to the one or more queries to the mass storage device, without terminating the one or more queries.
