implements org.apache.flink.api.common.operators.RecordOperator

CoGroupOperator that applies a CoGroupFunction to groups of records sharing the same key (one group per input). NOTE: The Record API is marked as deprecated. It is not being developed anymore and will be removed from the code at some point. See FLINK-1106 for more details.
