Flink 2.3 Ships Native S3 Filesystem

Apache Flink 2.3 introduces flink-s3-fs-native, a Hadoop-free S3 filesystem built specifically for Flink. The experimental opt-in plugin delivers measurable performance gains and supports RecoverableWriter for exactly-once sinks. It is already running in production at major technology companies, replacing the older Hadoop and Presto plugins that had configuration quirks and known bugs.
