DateTimeBucketer (flink-connector-filesystem 1.6.4 API)

java.lang.Object
- org.apache.flink.streaming.connectors.fs.bucketing.DateTimeBucketer<T>

所有已实现的接口:

Serializable, Bucketer<T>
```
public class DateTimeBucketer<T>
extends Object
implements Bucketer<T>
```
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 BucketingSink. The dateTimePath is determined based on the current system time and the user provided format string.
DateTimeFormatter is used to derive a date string from the current system time and the date format string with a timezone. 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/
