Struct tikv::storage::txn::commands::pessimistic_rollback::PessimisticRollback[][src]

pub struct PessimisticRollback {
    pub ctx: Context,
    pub keys: Vec<Key>,
    pub start_ts: TimeStamp,
    pub for_update_ts: TimeStamp,
}

Rollback pessimistic locks identified by start_ts and for_update_ts.

This can roll back an AcquirePessimisticLock command.

Fields

ctx: Contextkeys: Vec<Key>

The keys to be rolled back.

start_ts: TimeStamp

The transaction timestamp.

for_update_ts: TimeStamp
