Plagger::Rule::Deduped - Rule to get Deduped entries based on the database
# remove entries you already seen - module: Filter::Rule rule: module: Deduped path: /tmp/var.db
This rule de-duplicates entry based on cached index (database).
Specified path to the database. This config is dependent for the DB_File backend.
If set, this rule checks digest of entry, which is a MD5 hash of entry's title with body. Defaults to 0.
Kazuhiro Osawa created Plagger::Plugin::Cache in early days, which gives me a base idea of this module.
