partition layout defines how partition values can be extracted from the path. Use "%<colname>%" as token to extract the value for a partition column. With "%<colname:regex>%" a regex can be given to limit search. This is especially useful if there is no char to delimit the last token from the rest of the path or also between two tokens.

Connects to SFtp files Needs java library "com.hieronymus % sshj % 0.21.1" The following authentication mechanisms are supported -> public/private-key: private key must be saved in ~/.ssh, public key must be registered on server. -> user/pwd authentication: user and password is taken from two variables set as parameters. These variables could come from clear text (CLEAR), a file (FILE) or an environment variable (ENV)
