> The streaming FieldAccessors (keyedStream.keyBy(...)) have slightly different semantics compared to their batch counterparts. 
> Currently the streaming ones allow selecting a field within an array (which might be dangerous as the array typeinfo does not contain the length of the array, thus leading to a potential index out of bounds) and accept not only "*", but also "0" to select a whole type.
> This functionality should be either removed or documented. The latter can be achieved by effectively reverting [1]. Note that said commit was squashed before merging.
