Talend, combine tWaitForFile and tFileList

Question

I'm not so advanced in Talend, and I have got a job developed by a Talend expert which have a trick that i cannot understand, this is the tricky beginning of the job: The tricky beginning

The job will process any file exists in a specified folder, there is a producer process which write files continuously into the folder, so it have to process the already existing files and any new file will be created, the ammount of files is so huge and the target system is Linux.

I cant understand why he uses the tFileList while he can use only the tWaitForFile, it can retrieve existing and later created files.

Cordially.

Answer 1

TWaitForFile used to start file processing when there is files, the job should be run continiously but do nothing until TWaitForFile detect file in the directory, its simply a file-based trigger used as alternative for the trigger feature of the Entreprise edition.

Answer 2

you are right, tFileList or tWaitForFile component is sufficient to process exiting files and newly created file. But if you post job design or component property details for both the component then it will help to answer your question.
