I agree that many use cases of sparse data, uniqueness of the dimensions can't be guaranteed or you might not want to enforce the uniqueness. With the recent TileDB 2.0 release we introduced support for duplicates in sparse arrays which adds the support for multi-sets[1].

- jakebol 6y agoJust to note that language "duplicates in sparse arrays" doesn't make sense, if you allow for duplicates it is no longer an array by definition.
- DaiPlusPlus 6y agoArrays (vectors) can have duplicates - don’t you mean a set?
