Badger¶

Badger is an embedded database that stores Funnel task data in a local directory. It does not require a separate database server. Funnel uses BoltDB by default; select Badger in your configuration:

Database: badger

# The selected database already stores task events. This avoids opening
# another database as an additional event writer.
EventWriters:
  - log

Badger:
  Path: ./funnel-work-dir/funnel.badger.db

Save this configuration to a file, then start Funnel with it:

funnel server run --config /path/to/config.yaml

Badger.Path is a directory, relative to the server's working directory when given a relative path. Funnel creates it if it does not exist. Place it on persistent storage if task data must survive server or container restarts. To back it up, stop Funnel and copy the entire directory; restore it before restarting the server.

Use one Funnel server process per Badger directory. Badger does not implement the scheduler service required by Funnel's manual compute backend; use a different database backend for that configuration.
