测试并发时有:

[error] 函数执行失败（耗时 299ms） Error: errCode: -502001 database request fail | errMsg: document.update:fail [FailedOperation] (LockTimeout) Unable to acquire lock '{9101445243178794813: Database, 2183916215537712957}' within a max lock request timeout of '5ms' milliseconds.; at document.update api;

可否调整a max lock request timeout ?
