Abstract
A method for optimizing query compilation by tuning memory across a database cluster is provided. The method may include receiving, by a global memory tuner, memory configuration information from a plurality of nodes within the database cluster. The method may also include determining a node within the plurality of nodes having a least available memory value relative to a remainder of nodes within the plurality of nodes based on the received memory configuration information. The method may then include calculating a globally tuned memory value based on a memory value associated with the determined node. The method may further include determining a memory distribution based on the calculated globally tuned memory value. The method may also include sending the determined memory distribution to the plurality of nodes.
