> The Indexed record reader classes (IndexedReaderIterator, IndexedMutableReader) were introduced to allow the streaming operators to access the index of the last read channel from the input gate. This was a necessary step toward future input sorting operators.
> Unfortunately this untested feature was patched away by the following commit:
> https://github.com/apache/flink/commit/5232c56b13b7e13e2cf10dbe818c221f5557426d
> At some point we need to reimplement these features with proper tests.
