readLockMode property

String? readLockMode
getter/setter pair

Read lock mode for the transaction. Possible string values are:

  • "READ_LOCK_MODE_UNSPECIFIED" : Default value. If the value is not specified, the pessimistic read lock is used.
  • "PESSIMISTIC" : Pessimistic lock mode. Read locks are acquired immediately on read.
  • "OPTIMISTIC" : Optimistic lock mode. Locks for reads within the transaction are not acquired on read. Instead the locks are acquired on a commit to validate that read/queried data has not changed since the transaction started.

Implementation

core.String? readLockMode;
