On each tablet that stores NSchemeOp::TTTLSettings or NSchemeOp::TColumnDataLifecycle, we need to migrate all instances of these structures to new format with tiers, introduced in #11390. For that purpose, a normalizer must be added that, on initialization of a tablet, fills Tiers in all instances of migrated structures from local DB.

These tablets are:

  • SchemeShard
  • ColumnShard
  • Possibly DataShard
