Robert Metzger updated FLINK-2706: ---------------------------------- Component/s: filesystem-connector > Add support for streaming RollingFileSink to truncate / append on UNIX file > systems > ----------------------------------------------------------------------------------- > > Key: FLINK-2706 > URL: https://issues.apache.org/jira/browse/FLINK-2706 > Project: Flink > Issue Type: Improvement > Components: filesystem-connector, Streaming Connectors > Affects Versions: 0.10.0 > Reporter: Stephan Ewen > Assignee: Aljoscha Krettek > > Efficient exactly-once behavior needs the filesystem to support appending and > truncating files. > Since the UNIX file system API allows to append files and truncate files, we > can support perfect exactly-once behavior efficiently on all file systems > that expose a UNIX / POSIX-style interface (local FS, NFS, MapR FS). > Without this support, only Hadoop 2.7+ versions support proper exactly once > behavior. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
