Malthe Borch created NIFI-7597:
----------------------------------
Summary: Provide ExecuteStreamCommand option of streaming contents
over STDIN of an incoming flowfile as file
Key: NIFI-7597
URL: https://issues.apache.org/jira/browse/NIFI-7597
Project: Apache NiFi
Issue Type: Improvement
Reporter: Malthe Borch
ExecuteStreamCommand uses a
[BufferedOutputStream|https://docs.oracle.com/javase/7/docs/api/java/io/BufferedOutputStream.html]
as the stream which is attached as STDIN to the spawned child process.
However, some programs depend on STDIN being a file to enable certain modes of
operation. For example, Microsoft Azure's
[AzCopy|https://docs.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-v10]
utility.
This is an improvement proposal to add a toggle that controls whether to use a
buffered output stream or a file-based output stream.
