BloombergLP::bslstl::HashTable<UnorderedMapKeyConfiguration<basic_string<char> const, pair<basic_string<char> const, Json>>, TransparentHash, TransparentEqualTo, allocator<pair<basic_string<char> const, Json>>>::maxNumBuckets

Return a theoretical upper bound on the largest number of buckets that this hash-table could possibly have. Note that there is no guarantee that the hash-table can successfully maintain that number of buckets, or even close to that number of buckets without running out of resources.
