Struct solana_ledger::blockstore_db::columns::DeadSlots

source · 
pub struct DeadSlots;
Expand description

The dead slots column. This column family tracks whether a slot is dead.

A slot is marked as dead if the validator thinks it will never be able to successfully replay this slot. Example scenarios include errors during the replay of a slot, or the validator believes it will never receive all the shreds of a slot.

If a slot has been mistakenly marked as dead, the ledger-tool’s –remove-dead-slot can unmark a dead slot.

  • index type: u64 (see SlotColumn)
  • value type: bool
