Struct tikv::storage::txn::commands::ResolveLockReadPhase [−][src]
Scan locks for resolving according to txn_status.
During the GC operation, this should be called to find out stale locks whose timestamp is
before safe point.
This should followed by a ResolveLock.
Fields
ctx: Contexttxn_status: HashMap<TimeStamp, TimeStamp>Maps lock_ts to commit_ts. See ./resolve_lock.rs for details.
scan_key: Option<Key>Implementations
impl ResolveLockReadPhase[src]
pub fn new(
txn_status: HashMap<TimeStamp, TimeStamp>,
scan_key: Option<Key>,
ctx: Context
) -> TypedCommand<()>[src]
txn_status: HashMap<TimeStamp, TimeStamp>,
scan_key: Option<Key>,
ctx: Context
) -> TypedCommand<()>
Return a TypedCommand that encapsulates the result of executing this command.
