pyflink.datastream.connectors.file_system.BucketAssigner

class BucketAssigner(j_bucket_assigner)

A BucketAssigner is used with a file sink to determine the bucket each incoming element should be put into.

The StreamingFileSink can be writing to many buckets at a time, and it is responsible for managing a set of active buckets. Whenever a new element arrives it will ask the BucketAssigner for the bucket the element should fall in. The BucketAssigner can, for example, determine buckets based on system time.
