Wes McKinney updated ARROW-8990: -------------------------------- Description: While we have our own hash table implementation, it would be worthwhile to set up some benchmarks so that we can compare against std::unordered_map and some other thirdparty libraries for hash tables to know whether we should possibly use a thirdparty library. See e.g. https://tessil.github.io/2016/08/29/benchmark-hopscotch-map.html Libraries to consider: * https://github.com/sparsehash/sparsehash was: While we have our own hash table implementation, it would be worthwhile to set up some benchmarks so that we can compare against std::unordered_map and some other thirdparty libraries for hash tables to know whether we should possibly use a thirdparty library.
