/**
 * Service that can be used to invalidate archives or add archive references to a list so they will
 * be invalidated later.
 *
 * Archives are put in an "invalidated" state by setting the done flag to `ArchiveWriter::DONE_INVALIDATED`.
 * This class also adds the archive's associated site to the a distributed list and adding the archive's year month to another
 * distributed list.
 *
 * CronArchive will reprocess the archive data for all sites in the first list, and a scheduled task
 * will purge the old, invalidated data in archive tables identified by the second list.
 *
 * Until CronArchive, or browser triggered archiving, re-processes data for an invalidated archive, the invalidated
 * archive data will still be displayed in the UI and API.
 *
 * ### Deferred Invalidation
 *
 * Invalidating archives means running queries on one or more archive tables. In some situations, like during
 * tracking, this is not desired. In such cases, archive references can be added to a list via the
 * rememberToInvalidateArchivedReportsLater method, which will add the reference to a distributed list
 *
 * Later, during Piwik's normal execution, the list will be read and every archive it references will
 * be invalidated.
