      Description

      Currently, the cache implementation only tracks the actual data size against its memtracker, and not the overhead of the LRUHandle objects, keys, etc. This under-estimates the total cache memory usage. In the case of the pmem cache, we don't track memory at all, even though it can use some reasonable amount of memory if the PMEM is large.

      This will become higher priority if we start seeing users with large PMEM-based systems down the road.
