Case:
The memory size is taken into account within various components today:
- We set the default WiredTiger cache_size to approximately 1/2 of the memory size
- When ephemeral storage is in use we consider the memory limit in place to determine the default oplog size
- We set the tcmalloc cache size to 1/8th of the available memory
In all of these cases we should take the actual memory constraint that we're operating under into account rather than the total system memory – for example when running MongoDB within containers.
