    auto_heartbeat: bool,

Options for configuring a transaction.


kind: TransactionKind

Optimistic or pessimistic (default) transaction.

try_one_pc: bool

Try using 1pc rather than 2pc (default is to always use 2pc).

async_commit: bool

Try to use async commit (default is not to).

read_only: bool

Is the transaction read only? (Default is no).

retry_options: RetryOptions

How to retry in the event of certain errors.

check_level: CheckLevel

What to do if the transaction is dropped without an attempt to commit or rollback

auto_heartbeat: bool

Whether heartbeat will be sent automatically


impl TransactionOptions[src]

pub fn new_optimistic() -> TransactionOptions[src]

Default options for an optimistic transaction.

pub fn new_pessimistic() -> TransactionOptions[src]

Default options for a pessimistic transaction.

pub fn use_async_commit(self) -> TransactionOptions[src]

Try to use async commit.

pub fn try_one_pc(self) -> TransactionOptions[src]

Try to use 1pc.

pub fn read_only(self) -> TransactionOptions[src]

Make the transaction read only.

pub fn no_resolve_locks(self) -> TransactionOptions[src]

Don’t automatically resolve locks and retry if keys are locked.

pub fn no_resolve_regions(self) -> TransactionOptions[src]

Don’t automatically resolve regions with PD if we have outdated region information.

pub fn retry_options(self, options: RetryOptions) -> TransactionOptions[src]

Set RetryOptions.

pub fn drop_check(self, level: CheckLevel) -> TransactionOptions[src]

Set the behavior when dropping a transaction without an attempt to commit or rollback it.
