-----------------------------------
Assignee: Claus Ibsen
> camel-sftp: check for existance of remote directory using ls is very slow
> -------------------------------------------------------------------------
>
> Key: CAMEL-14947
> URL: https://issues.apache.org/jira/browse/CAMEL-14947
> Project: Camel
> Issue Type: Improvement
> Components: camel-ftp
> Affects Versions: 2.25.1
> Reporter: Christian Nedregård
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 3.3.0, 2.25.2
>
>
> In CAMEL-12733 the check for existing directories used by autoCreate was
> changed from {{ChannelSftp.cd}} to {{ChannelSftp.ls}} to fix a Windows
> specific issue.
> {{cd}} is a remote operation while {{ls}} will actually load the full
> directory listing and load it over the wire. This happens for every file that
> are to be written. If the remote directory has a lot of files this has a
> heavy performance penalty.
> In our case the directory some times contains 50.000+ files. Without
> autoCreate the writes take a few milliseconds. With autoCreate it takes up to
> 10 seconds due to the huge directory listing being generated and loaded over
> the wire for every single file to be written.
> This can be solved by reverting the directory check to a remote operation
> such as {{cd}} and fixing the Windows specific issue in another way.
> If it turns out that {{ls}} has to be used (unlikely) please note that there
> is another variant that takes a selector that enables you to abort the actual
> loading of the listing:
> {code:java}
> ls(String path, LsEntrySelector selector){code}
