Note that these examples are *not* exhaustive and you can use S3 in other
places as well, including your [high availability setup]({{< ref
"docs/deployment/ha/overview" >}}) or the [EmbeddedRocksDBStateBackend]({{< ref
"docs/ops/state/state_backends" >}}#the-rocksdbstatebackend); everywhere that
Flink expects a FileSystem URI (unless otherwise stated).
-For most use cases, you may use one of our `flink-s3-fs-hadoop` and
`flink-s3-fs-presto` S3 filesystem plugins which are self-contained and easy to
set up.
-For some cases, however, e.g., for using S3 as YARN's resource storage dir, it
may be necessary to set up a specific Hadoop S3 filesystem implementation.
+## S3 FileSystem Implementations
-### Hadoop/Presto S3 File Systems plugins
+Flink provides three independent S3 filesystem implementations, each with
different trade-offs:
+
+- **Native S3 FileSystem** (`flink-s3-fs-native`): Built directly on AWS SDK
v2 with async I/O and parallel transfers, removing the dependency from Hadoop
entirely. Supports both checkpointing and the FileSink in a single plugin,
removing the need to choose between Presto (checkpointing) and Hadoop
(FileSink).
[Benchmarks](https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=406620396)
show ~2x higher checkpoint throughput (~200 MB/s vs ~90 MB/s) compared to the
Presto implementation at state sizes up to 15 GB. **Experimental** in Flink 2.3.
+- **Presto S3 FileSystem** (`flink-s3-fs-presto`): Based on Presto project
code. The proven choice for checkpointing in production.
+- **Hadoop S3 FileSystem** (`flink-s3-fs-hadoop`): Based on Hadoop project
code. Supports both checkpointing and the FileSink.
Review Comment:
Am I missing something, you say` Hadoop (FileSink)` but then say `Based on
Hadoop project code. Supports both checkpointing and the FileSink.`
