-----------------------------------
Summary: Sink for eventually consistent file systems
Key: FLINK-6306
URL: https://issues.apache.org/jira/browse/FLINK-6306
Project: Flink
Issue Type: New Feature
Components: filesystem-connector
Reporter: Seth Wiesman
Assignee: Seth Wiesman
Currently Flink provides the BucketingSink as an exactly once method for
writing out to a file system. It provides there guarantees by moving files
through several stages and deleting or truncating files that get into a bad
state. While this is a powerful abstraction, it causes issues with eventually
consistent file systems such as Amazon's S3 where must operations (ie rename,
delete, truncate) are not guaranteed to become consistent within a reasonable
amount of time. Flink should provide a sink that provides exactly once writes
to a file system where only PUT operations are considered consistent.
