Struct rocksdb::OptimisticTransactionOptions

pub struct OptimisticTransactionOptions { /* private fields */ }

Implementations

impl OptimisticTransactionOptions

pub fn new() -> OptimisticTransactionOptions

pub fn set_snapshot(&mut self, snapshot: bool)

Specifies use snapshot or not.

Default: false.

If a transaction has a snapshot set, the transaction will ensure that any keys successfully written(or fetched via get_for_update) have not been modified outside the transaction since the time the snapshot was set. If a snapshot has not been set, the transaction guarantees that keys have not been modified since the time each key was first written (or fetched via get_for_update).

Using snapshot will provide stricter isolation guarantees at the expense of potentially more transaction failures due to conflicts with other writes.

Calling set_snapshot will not affect the version of Data returned by get methods.
