[esb-issues] [JBoss JIRA] Created: (JBESB-1153) File Gateway: Consume only a single file at a time

File Gateway: Consume only a single file at a time -------------------------------------------------- Key: JBESB-1153 URL: http://jira.jboss.com/jira/browse/JBESB-1153 Project: JBoss ESB Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Transports Affects Versions: 4.2 Reporter: Burr Sutter Assigned To: Mark Little Fix For: 4.3 The current File gateway consumes files at a rate faster than the internal/native listener (typically JMS-based) and its associated action chain. This request is for a configuration property that causes the rate of consumption of the file gateway to match the underlying internal/native listener. Basically a file would not be pulled from disk until it has completely passed through the action chain. Here are some notes related to this use case: I have 1000+ files which are very huge in size and when all the files are kept in the folder they are read at same time and placed in configured JMS Queue. - When all the files are placed in Queue there is a chance that the size of messages in Queue may exceed and it may not accept new messages? Or - Sometimes the case may be like the input folder is monitored by one person and the message processing is monitored by other person. In this case when all the files are read at once it gives a wrong assumption that all files are processed but where as due to some application failure the messages may still be in queue. Or - Its always a good option to be able to see how many messages are still in process in the folder rather than browsing the JMS queue and looking for Queue depth. In this case if you look at Queue depth sometimes it may be give you wrong count of messages as there is a chance that some other application also put message some messages into the same queue, when Queue is configured for application sharing. Or - If you want to replace a single file out of 1000+ files in the input folder while in middle of processing the files, it will be easy if the files are read one at a time rather going and deleting the messages from JMS queue after they are read at once and placed in Queue. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
