------------------------------------------
Summary: Introducing checkpoint file manager based on Hadoop's
Abortable interface
Key: SPARK-40039
URL: https://issues.apache.org/jira/browse/SPARK-40039
Project: Spark
Issue Type: Improvement
Components: Structured Streaming
Affects Versions: 3.4.0
Reporter: Attila Zsolt Piros
Assignee: Attila Zsolt Piros
Currently on S3 the checkpoint file manager (called
FileContextBasedCheckpointFileManager) is based on rename. So when a file is
opened for an atomic stream a temporary file used instead and when the stream
is committed the file is renamed.
But on S3 a rename will be a file copy. So it has some serious performance
implication.
But on Hadoop 3 there is new interface introduce called *Abortable* and
*S3AFileSystem* has this capability which is implemented by on top S3's
multipart upload. So when the file is committed a POST is sent
([https://docs.aws.amazon.com/AmazonS3/latest/API/API_CompleteMultipartUpload.html])
and when aborted a DELETE will be send
([https://docs.aws.amazon.com/AmazonS3/latest/API/API_AbortMultipartUpload.html])
