-------------------------------------
Summary: Consolidate streaming FieldAccessor functionality
Key: FLINK-5156
URL: https://issues.apache.org/jira/browse/FLINK-5156
Project: Flink
Issue Type: Task
Reporter: Márton Balassi
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.
