Sorry for the long subject ! I'm running a single query on a single node Drill setup.
I assumed that setting the *planner.memory.max_query_memory_per_node* property controls the max amount of memory (in bytes) for each running on a single node. Which means that in my setup, the *direct.used* metric in the metrics page should never exceed that value in my case. But it did and drastically. I assigned *34359738368* (32 GB) to the *planner.memory.max_query_memory_per_node* option but while monitoring the *direct.used* metric, I found that it reached *51640484458* (~48 GB). What did I mistakenly do\interpret ? Thanks, Gelbana
