Interface TimestampedInputSplit

All Superinterfaces:

Comparable<TimestampedInputSplit>, org.apache.flink.core.io.InputSplit, Serializable

All Known Implementing Classes:

TimestampedFileInputSplit

public interface TimestampedInputSplit
extends org.apache.flink.core.io.InputSplit, Comparable<TimestampedInputSplit>

An extended InputSplit that also includes information about:

• The modification time of the file this split belongs to.
• When checkpointing, the state of the split at the moment of the checkpoint.

This class is used by the ContinuousFileMonitoringFunction and the ContinuousFileReaderOperator to perform continuous file processing.

Method Summary

Modifier and Type	Method	Description
long	getModificationTime()
Serializable	getSplitState()
default void	resetSplitState()	Sets the state of the split to null.
void	setSplitState(Serializable state)	Sets the state of the split.

Method Details

setSplitState

void setSplitState(Serializable state)

Sets the state of the split. This information is used when restoring from a checkpoint and allows to resume reading the underlying file from the point we left off.

* This is applicable to FileInputFormats that implement the CheckpointableInputFormat interface.

getSplitState

Serializable getSplitState()

Returns:

the state of the split.

resetSplitState

default void resetSplitState()

Sets the state of the split to null.

getModificationTime

long getModificationTime()

Returns:

The modification time of the file this split belongs to.
