The `AdaptiveScheduler` requires the `MD5SignatureParseFilter` to be configured so that the `signature` metadata field is populated. The scheduler also persists its current `fetchInterval` and the metadata used to detect content changes. The `last-modified` field (written when `scheduler.adaptive.setLastModified` is enabled) and `protocol.etag` allow conditional requests (`If-Modified-Since` / `If-None-Match`).
