[jira] [Updated] (FLINK-12793) Add localKeyBy API to DataStream
[ https://issues.apache.org/jira/browse/FLINK-12793?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
vinoyang updated FLINK-12793:
-----------------------------
Description:
We need to provide a series of {{localKeyBy}} methods in {{DataStream}}. They are:
{code:java}
KeyedStream<T, Tuple> localKeyBy(int… fields);
KeyedStream<T, Tuple> localKeyBy(Keys<T> keys);
<K> KeyedStream<T, K> localKeyBy(KeySelector<T, K> keySelector);
<K> KeyedStream<T, K> localKeyBy(KeySelector<T, K> keySelector, TypeInformation<K> keyType);
{code}
And we also need to do some changes when jobs compiling.
