方法详细资料

validateTransformationUid

public static void validateTransformationUid(StreamGraph streamGraph,
                                             org.apache.flink.api.dag.Transformation<?> transformation)

Throw IllegalStateException if the PhysicalTransformation's uid or hash is not set when auto generate uid is disabled.

参数:

streamGraph - The given graph that the transformation is added to

transformation - The transformation needed to validate

configureBufferTimeout

public static <T> void configureBufferTimeout(StreamGraph streamGraph,
                                              int nodeId,
                                              org.apache.flink.api.dag.Transformation<T> transformation,
                                              long defaultBufferTimeout)

Configure a stream node's buffer timeout according to the given transformation.

参数:

streamGraph - The StreamGraph the node belongs to

nodeId - The node's id

transformation - A given transformation

defaultBufferTimeout - The default buffer timeout value
