----------------------------------------
Summary: SFTP: Enable configuration of bulk requests
Key: CAMEL-9808
URL: https://issues.apache.org/jira/browse/CAMEL-9808
Project: Camel
Issue Type: Improvement
Components: camel-ftp
Reporter: Thomas Küstermann
JSch uses multiple requests to pull files from / push files to a SFTP server.
The number of bulk requests can be configured via
{{ChannelSftp#setBulkRequests(int)}}. The API documentation states that
increasing this value may slightly improve file transfer speed at the cost of
memory usage.
The configuration option should be made available in Camel.
h4. Background
I came across an issue with a specific SFTP server product. I tracked this
issue down to the way bulk requests are sent to the SFTP server. To cut a long
story short ([details

setting the number of bulk requests to 1 solves the problem, so it would be
nice to have this option available via Camel.
