Where I can see "hash join and semi join" in scidb?


#1

Hi, there!
I’m Cherry. I’m studying SciDB recently. I know join is implemented with merge_sort join. Is it implemented in the file called “SortArray.cpp”,“MergeArray.cpp” and “SortMergeArray.cpp”?
Cross_join is implemented with hash join and semi join. But I can’t find the “HashJoinArray.cpp” which like “SortMergeArray.cpp”? So which file is it in?
Thanks a lot!
