Struct pallet_grandpa::migrations::CleanupSetIdSessionMap
source · pub struct CleanupSetIdSessionMap<T>(_);Expand description
This migration will clean up all stale set id -> session entries from the
SetIdSession storage map, only the latest max_set_id_session_entries
will be kept.
This migration should be added with a runtime upgrade that introduces the
MaxSetIdSessionEntries constant to the pallet (although it could also be
done later on).
