------------------------------------------------------------
{code:java}
df %>% select(x, y) %>% distinct()
# or
df %>% distinct(x, y){code}
is equivalent to
{code:java}
df %>% group_by(x, y) %>% summarize(){code}
so when ARROW-13543 gives us the ability to do the latter, we will be able to
implement the former.
