keys with NULL are not equal to anything else and should be considered unique
when we definitely know row on one side won't match any row on other side (e.g. NULL in keys), we can skip processing and ignore or return row with NULL added any side of INNER, LEFT SEMI, RIGHT SEMI, right side of LEFT, LEFT ONLY, left side of RIGHT, RIGHT ONLY -> skip/ignore left side of LEFT, LEFT ONLY, right side of RIGHT, RIGHT ONLY, any side of FULL, EXCLUSION: -> add NULL to other side and return kind | left side | right side -----------+--------------------+----------- INNER | drop | drop LEFT SEMI | drop | drop RIGHT SEMI | drop | drop LEFT | return row + NULL | drop LEFT ONLY | return row + NULL | drop RIGHT | drop | return NULL + row RIGHT ONLY | drop | return NULL + row FULL | return row + NULL | return NULL + row EXCLUSION | return row + NULL | return NULL + row
try to use it once, if it turned out to be inefficient -- just drop it
