BuffaloFQ - a method of moving files via a file system queue
The objective of BuffaloFQ is to provide a very simple and reliable method of moving files around an architecture.
Background, Examples, and FAQ
Please see the Wiki: https://github.com/kenfar/buffalofq/wiki
Installation:
$ pip install buffalofq
Configuration:
Most configuration is handled through a simple yaml file, that is kept in the xdg-compliant config directory. On linux this would be:
- $HOME/.config/buffalofq_mover/[config-name1].yml
- $HOME/.config/buffalofq_mover/[config-name2].yml
- $HOME/.config/buffalofq_mover/[config-name3].yml
Config example:
- name: ids_to_load #
- status: enabled # choices are: enabled, disabled
- polling_seconds: None # delay in seconds between checks for new files, defaults to 300
- limit_total: -1 # choices: -1 (run continuously), 0 (run until source_dir is empty), [some number] run until this number have been moved.
- port: None # defaults to 22
- key_filename: None # defaults to id_buffalofq_rsa
- log_dir: /data/logs # location buffalofq_mover will write its logs
- log_level: None # choices are: info, warning, error, critical, defaults to debug
- sort_key: time # choices are: None, name, or name of a field within filename, defaults to None
- source_host: localhost # must be localhost at this time
- source_user: None # not yet used, defaults to current userid
- source_dir: /data/output #
- source_fn: '*' # wild-card for selecting source files
- source_post_dir: /data/archive #
- source_post_action: move # choices: move, delete, None
- dest_host: datawarehouse #
- dest_user: None # used to log into dest_host, defaults to current userid
- dest_dir: /data/input #
- dest_fn: None # needed if dest_post_action is symlink or move
- dest_post_dir: None # not used yet
- dest_post_action: None # choices: symlink, move, None
Run:
To run once, you can simply run it like:
- $ ./buffalofq_mover --config-name [config-name1]
A trivial way to keep it running continuously:
- $ nohup ./buffalofq_mover --config-name [config-name1] &
