Package org.apache.flink.runtime.asyncprocessing

Class RecordContext<K>

java.lang.Object

org.apache.flink.runtime.asyncprocessing.ReferenceCounted<RecordContext.DisposerRunner>

org.apache.flink.runtime.asyncprocessing.RecordContext<K>

Type Parameters:

K - The type of the key inside the record.

public class RecordContext<K>
extends ReferenceCounted<RecordContext.DisposerRunner>

A context that preserves the necessary variables required by each operation, all operations for one record will share the same element context.

Reference counting mechanism, please refer to ContextAsyncFutureImpl.
