getForUpdateTs

public long getForUpdateTs()

 Each locking command in a pessimistic transaction has its own timestamp. If locking fails, then
 the corresponding SQL statement can be retried with a later timestamp, TiDB does not need to
 retry the whole transaction. The name comes from the `SELECT ... FOR UPDATE` SQL statement which
 is a locking read. Each `SELECT ... FOR UPDATE` in a transaction will be assigned its own
 timestamp.
 

uint64 for_update_ts = 6;

public long getWaitTimeout()

 Time to wait for lock released in milliseconds when encountering locks.
 0 means using default timeout in TiKV. Negative means no wait.

getForce

@Deprecated
public boolean getForce()

已过时。

 If it is true, TiKV will acquire the pessimistic lock regardless of write conflict
 and return the latest value. It's only supported for single mutation.

getReturnValues

public boolean getReturnValues()

 If it is true, TiKV will return values of the keys if no error, so TiDB can cache the values for
 later read in the same transaction.
 When 'force' is set to true, this field is ignored.
 

bool return_values = 10;

uint64 min_commit_ts = 11;

指定者:

getMinCommitTs 在接口中 Kvrpcpb.PessimisticLockRequestOrBuilder

getCheckExistence

public boolean getCheckExistence()

 If set to true, it means TiKV need to check if the key exists, and return the result in
 the `not_founds` feild in the response. This works no matter if `return_values` is set. If
 `return_values` is set, it simply makes no difference; otherwise, the `value` field of the
 repsonse will be empty while the `not_founds` field still indicates the keys' existence.
