# Clear all repository metadata from the datastore (e.g. Fedora, Postgres)
# and from Solr.
#
# @note WARNING: DO NOT USE IN PRODUCTION! The methods in this class are destructive.
# Data can not be recovered.
#
# @note When using Wings adapter, which wraps ActiveFedora, the persister wipe!
# method clears both Fedora and Solr. Optionally, an index_adapter may also
# be set to use Valkyrie to write to a second Solr core. If the Hyrax index
# adapter is the NullIndexingAdapter, that means that Valkyrie is not being
# used to index the repository metadata and does not need to be cleared using
# the Hyrax index adapter.
#
# When using other Valkyrie persistence adapters, wipe! only clears the repository
# metadata from the datastore (e.g. ORM table in Postgres). The index adapter
# is used to clear metadata from Solr.
