[jira] [Created] (CAMEL-5558) Add fileExist option to write file
with a new name in case file already exists
Claus Ibsen created CAMEL-5558:
----------------------------------
Summary: Add fileExist option to write file with a new name in case file already exists
Key: CAMEL-5558
URL: https://issues.apache.org/jira/browse/CAMEL-5558
Project: Camel
Issue Type: New Feature
Components: camel-core, camel-ftp
Affects Versions: 2.10.0
Reporter: Claus Ibsen
Fix For: Future
See nabble
http://camel.465427.n5.nabble.com/Camel-FTP-component-Append-a-sequence-number-if-the-filename-already-exists-tp5718469.html
We should allow to configure fileExists=RenameAndRetry option, which allows you to rename the file and retry writing the file again, in case there already exists a file.
The trick is to find a optimal solution if you append a sequence number to a file. And when there is a lot of files. You kinda want to know what is the highest filename, (some way of listing and sorting).
Maybe a way to get a list of existing files based on a file name pattern, and a sort configuration. Then people can check in the list, to find a free sequence number to use etc.

[jira] [Commented] (CAMEL-5558) Add fileExist option to write file

----------------------------------------
Hello guys,
Yes, it would be awesome if this could be configurable in such a way that you could place the sequence as an expression in the destination file name and also specify the format of the sequence, example 01, 0001 or 000001.
Use case:
Files get transfered from multiple sources into a single location. These files all have names generated by the sources, eg:
{code}
File1.dat
File6.dat
File17.dat
Data1.dat
20120904-001.dat
{code}
These files now have to be re-sequenced with a specific naming convention when they are consumed and produced to the upstream system:
{code}
CUST.FILE.20120904.000001.DAT
CUST.FILE.20120904.000002.DAT
CUST.FILE.20120904.000003.DAT
CUST.FILE.20120904.000004.DAT
CUST.FILE.20120904.000005.DAT
{code}
It would be nice if you could pick up the last sequence from the destination that the producer is writing to.
