Timo Walther commented on FLINK-5304:
-------------------------------------

I'm fine with this change but what happens with {{outerApply}}? We should also 
rename it to {{leftOuterJoin()}} to be consistent.

> Change method name from crossApply to join in Table API

> Currently, the UDTF in Table API is used with {{crossApply}}, but is used 
> with JOIN in SQL. UDTF is something similar to Table, so it make sense to use 
> {{.join("udtf(c) as (s)")}} in Table API too, and join is more familiar to 
> users than {{crossApply}}.
