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

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