Samba component

The Samba component is able to connect to file servers that support the SMB/CIFS protocol (Windows File Sharing), both as an inbound component (reading files) and as an outbound component (writing files).

Basic configuration​

The Samba component has the following basic configuration options:

Force inbound​

Description

Settings this to Yes will force the component to turn from outbound to inbound and consume a file from the (S)FTP(S) server. This has the same behavior as putting the component below an Enrich component that is set to Override. This means that the current body will be overridden with the new body of the consumed file.

Remarks

  • Only available when component is outbound.
  • Only one file will be consumed when the component is forced to be inbound.
  • This options only becomes visible when another component is connected on the left side of this component.

Domain​

Description

Specify the Windows domain the user belongs to.

Host​

Description

URL or IP address of the file server e.g. smb.example.org, 149.210.209.32.

Port​

Description

Specify a custom TCP/IP port, by default 139 is used

Username​

Description

The name of the user account for the file server.

Password​

Description

The password that belongs to the user account for the file server.

Path​

Description

Path to indicate which share and which directory it should poll, like share/directory/. In case of inbound this is the directory where Dovetail will be picking up files from, if used as outbound this is the directory where Dovetail will write files to.

Remarks

  • If you include a / at the end of the path, the component will try to copy the whole file path and not the file name by itself.

File Name​

Description

Get specific file with this name when inbound or set file name when outbound.

Charset​

Description

Specifies the encoding of the file.

Remarks

File Exist​

Options

  • Override (default)
  • Append
  • Ignore
  • Fail

Description

Specify what to do if a file with the same name already exists.

Remarks

  • Only available when component is outbound.

Delay​

Description

Milliseconds to wait before the next poll of the file/directory.

Remarks

  • Only available when the component is inbound.

Advanced configuration​

The Samba component has the following advanced configuration options:

Auto Create​

Options

  • Yes (default)
  • No

Description

Automatically creates missing directories in the file path.

Remarks

  • Only available when component is outbound.

Recursive​

Options

  • Yes
  • No (default)

Description

When inbound, specifies whether Dovetail should process files only in the specified path (No) or in all subdirectories of the path too (Yes).

Remark

When set to Yes you must make sure that your exclude pattern will ignore the directory were you place the processed files, otherwise you will end up with a infinite loop.

Delete file​

Options

  • Yes
  • No (default)

Description

If set to Yes, the file will be deleted after it is processed.

Remarks

  • Only available when the component is inbound.
  • When set to Yes, the Move option is ignored and hidden.

Move​

Description

Relative path to folder where files should be moved to when done processing.

Create and move files into this folder when done processing. This should be a relative path. In order to move to higher paths use ../[folder name] or ../../[folder name].

Remarks

  • Only available when the component is inbound.
  • Only used and shown when Delete file is set to No.
  • Files can be moved to folders higher in the hierarchy with .., for example: ../[folder name] or ../../[folder name].
  • The default behavior is to create a directory named .dovetail and move everything into that directory when files are processed. However some (S)FTP(S) servers don't allow creating .\* files or directories. In this case, you need to change the name of the .dovetail directory to something that is accepted by the server.

Local work directory​

Description

Local temporary directory where files are copied for processing. This is used to store the remote file content directly in local files to avoid loading the content into memory. This is beneficial when working with larger remote files and it can conserve memory.

Remarks

  • Only available when the component is inbound.

Read lock​

Options

  • none
  • changed

Description

If set to changed, only consumes the files if it has exclusive read-lock on the file (i.e. the file is not in-progress or being written). It will wait until the file lock is granted.

Remarks

  • Only available when component is inbound.

When set to changed:

  • It requires write permissions on the (S)FTP(S) server.
  • It uses file length or file modification timestamp to detect whether the file is currently being changed or not. It will at least use 1 second to check this and there will also be some time between each check, so consuming files will be slower.
  • It will require a lock on the latest file until a new file has been written to the (S)FTP(S) server. It will not be processed until a new file has been dropped at the ftp server.

Include​

Description

Used to include files, if the filename matches the regular expressions pattern.

Remarks

  • Only available when the component is inbound.

Exclude​

Description

Used to exclude files, if the filename matches the regular expressions pattern.

Remarks

  • Only available when the component is inbound.

Initial delay​

Description

Milliseconds to wait before polling the file/directory starts.

Remarks

  • Only available when the component is inbound.

Producing large text files (> 10 MB)​

When producing large text files like XML or JSON you might want to leave the charset option empty. This tells Dovetail that it should read the file as binary which means it does not have to read all the file's content into memory to validate the charset. This is better for it's performance and can prevent errors parsing the file later on in the flow.

Remarks​

  • Moving or deleting files: When the DeleteFile is set to true, the Move option is ignored. When the DeleteFile property is not set to true, processed files will be moved to a .camel directory.
  • ReadLock This option is used while 'consuming', to only poll the files if it has exclusive read-lock on the file (i.e. the file is not in-progress or being written). The options are none or changed.
  • Move the default behavior is to create a .camel directory and move everything into that directory when it's processed.
  • Recursive Watch out when enabled! You must make sure that your Exclude pattern will ignore the directory were you place the processed files, otherwise you will end up with a infinite loop!
  • The component doesn't support DFS file shares.
  • This component only supports version 1 of the SMB protocol.
