standalone C++ API for lock-free concurrent hashmap?

[colin-heberling]

Hi,

I'd like to use just the multithreaded hashmap implementation from jellyfish in a C++ application, as well as the key encoding, if that's separate. Is this available anywhere? One line from the publication seemed to indicate that it was, but I don't see anything obvious here.

Thanks!

Hi colin,

Jellyfish does have a library that you can use independently of the executable itself. It comes with a lot more things than just the hash though, but it should work. When you compile and install jellyfish, it should install the header files and the shared library as well.

Extracting the hashmap as a self-contained small number of header files would be nice indeed.

I've looked briefly over the files contained in the library before, but it's not clear to me where the hash table is located. How difficult do you think it would be for you to extract it into a separate module (ideally as a separate project, I don't think it would make sense to compromise jellyfish of course)?

And additionally, is the hash table written as a template or are your chosen data types hard-coded?
