Last time I checked out VictoriaMetrics it had something akin to a memory leak when writing evenly to large numbers of distinct keys -- attempting to cache all the data in RAM and not freeing it even under high memory pressure (it's been awhile, but iirc it had a hard-coded 1hr expiry). Does that sound like a behavior that would still exist in the current design?
