SFTP Client GET Service - input parameter to set a max number of files processed

We are using the operation SFTPClientGet and the parameter RemoteFilePattern to do a multiple get. See the below example.

We would like to have an input parameter allowing us to set a maximum number of files processed during one sftp get operation.


<operation>

<participant name="SFTPClientGet"/>
<output message="xout">
<assign to="RemoteFilePattern">myFiles.*.dat</assign>
<assign to="RetrieveErrorSetSuccess">NO</assign>
<assign to="SessionToken" from="SFTPtoken/text()"/>
</output>
<input message="xin">
<assign to="." from="*"/>
</input>
</operation>
What is your industry? Automotive
How will this idea be used?

During a multiple get with the parameter RemoteFilePattern, we cannot control the number of files retrieved. Then, if the remote sftp server produce thousands of files matching the RemoteFilePattern, it can lead us to a flood situation.

Therefore we would like to have an input paramter allowing us to set a maximum number of files processed during one sftp get operation.

At the moment the workaround is to first list the directory and count the number of files available before making the sftp get. If the number of files available is too high for us, we can decide to not execute the sftp get. But this workaround is not convenient because we never retrieve any file at all until human intervention on the remote sftp server.

    This enhancement would help a lot to secure the SI environment from slowdowns as there is no method to ensure the partner is cleaning up the source directory efficiently.  The SFTPClientGet generally pulls a selected wildcard list of files. As the command doesn't contain a restrictive setting, all files corresponding to the pattern will be pulled.  

    It is important to protect the server side as the remote side is out of control for the SI administrators !

    This is a great idea. I've built custom workflows to accomplish this ask; however, throttling mechanisms for all the SFTP Operations would be great. Extend this to file size as well. e.g. after picking up 1 GB worth of files, continue the rest of the BP.

    In the case of SFTP LS, a limit on the data coming back would be nice especially since Listing a directory too large will crash the adapter.
