// if in gluster, will consume some duplicated edis
        //from("file:camel-in-edi?include=.*//.txt&delay=300&idempotent=true&idempotentRepository=#fileStore&move=done/${file:name}")
       
        //The underlining config causes the two servicemixes working on the same gluster  work alternately
        //from("file:camel-in-edi?include=.*//.txt&delay=300&readLock=changed&readLockTimeout=0&maxMessagesPerPoll=100&idempotent=true&idempotentRepository=#fileStore&delete=true&inProgressRepository=#file_inProgress")
       
        //this will cause the gluster dead soon ,because of the idempotentRepository=#fileStore&delete=true&inProgressRepository=#file_inProgress
        //from("file:camel-in-edi?include=.*//.txt&delay=300&readLock=fileLock&readLockTimeout=0&maxMessagesPerPoll=100&idempotent=true&idempotentRepository=#fileStore&delete=true&inProgressRepository=#file_inProgress")
       
        //this will cause 2 servicemix grab the edi filelock forever, cause deadlock
        //from("file:camel-in-edi?include=.*//.txt&delay=300&readLock=fileLock&readLockTimeout=0&maxMessagesPerPoll=100&delete=true")
