org.apache.flink.streaming.connectors.fs.DateTimeBucketer

所有已实现的接口:

Serializable, Bucketer

已过时。

use DateTimeBucketer instead.

@Deprecated
public class DateTimeBucketer
extends Object
implements Bucketer

A Bucketer that assigns to buckets based on current system time.

The DateTimeBucketer will create directories of the following form: /{basePath}/{dateTimePath}/. The basePath is the path that was specified as a base path when creating the RollingSink. The dateTimePath is determined based on the current system time and the user provided format string.

SimpleDateFormat is used to derive a date string from the current system time and the date format string. The default format string is "yyyy-MM-dd--HH" so the rolling files will have a granularity of hours.

Example:

     Bucketer buck = new DateTimeBucketer("yyyy-MM-dd--HH");
 

This will create for example the following bucket path: /base/1976-12-31--14/

public boolean shouldStartNewBucket(org.apache.hadoop.fs.Path basePath,
                                    org.apache.hadoop.fs.Path currentBucketPath)

已过时。

从接口复制的说明: Bucketer

Returns true when a new bucket should be started.

指定者:

shouldStartNewBucket 在接口中 Bucketer

currentBucketPath - The bucket Path that is currently being used.

getNextBucketPath

public org.apache.hadoop.fs.Path getNextBucketPath(org.apache.hadoop.fs.Path basePath)

已过时。

从接口复制的说明: Bucketer

Returns the Path of a new bucket file.

指定者:

getNextBucketPath 在接口中 Bucketer

参数:

basePath - The base path containing all the buckets.

返回:

The complete new Path of the new bucket. This should include the basePath and also the subtaskIndex tp avoid clashes with parallel sinks.

toString

public String toString()

已过时。

覆盖:

toString 在类中 Object

setClock

public static void setClock(Clock newClock)

已过时。

This sets the internal Clock implementation. This method should only be used for testing
