Struct tikv::storage::txn::commands::check_secondary_locks::CheckSecondaryLocks

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

Check secondary locks of an async commit transaction.

If all prewritten locks exist, the lock information is returned. Otherwise, it returns the commit timestamp of the transaction.

If the lock does not exist or is a pessimistic lock, to prevent the status being changed, a rollback may be written.

Fields

ctx: Context

keys: Vec<Key>

The keys of secondary locks.

start_ts: TimeStamp

The start timestamp of the transaction.

Implementations

impl CheckSecondaryLocks

pub fn new(
    keys: Vec<Key>,
    start_ts: TimeStamp,
    ctx: Context
) -> TypedCommand<SecondaryLocksStatus>

Return a TypedCommand that encapsulates the result of executing this command.
