growt
This is a header only library offering a variety of dynamically growing concurrent hash tables. That all work by dynamically migrating the current table once it gets too full. (by TooBiased)

The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Experiences with Concurrent Hash Map Libraries
growt shows impressive benchmark results in this paper compared to folly, TBB, junction, and libcuckoo. However, it was not in good shape to be used as a production dependency. I had several issues and compilation errors here, here, and here.

Cuckoo Hashing Library with variable hash functions and buckets
https://github.com/efficient/libcuckoo - I'm not so sure about this one as I'm not too familiar with C++

Experiences with Concurrent Hash Map Libraries
In the case of libcuckoo a lock is obtained for iterating the elements. See here. This is done infrequently to prevent performance impact.
What are some alternatives?
