   Unless I am missing something, this is "safe" if `METADATA_CACHE_MAX_BYTES` 
is set to a relatively low value, right?
   
   In the absence of testing showing that there is measurable performance 
degradation due to churning large strings in the heap when 
`METADATA_CACHE_MAX_BYTES` is set to e.g. 10000, I posit that the performance 
is probably OK for now. Indeed, in the limited testing I have done, performance 
is actually much better compared to a solution that has no caching and always 
needs to go to object storage for the metadata.
