Struct Options

pub struct Options {
    pub parallel: Option<bool>,
    pub prefetch: Option<bool>,
    pub prefetch_size: Option<u64>,
    pub transaction_timeout: Option<Duration>,
    pub schema_lock_acquire_timeout: Option<Duration>,
    pub read_any_replica: Option<bool>,
}

TypeDB transaction options. TypeDBOptions object can be used to override the default server behaviour. Options are specified using properties assignment.

Examples

let options = Options::new().explain(true);

Fields

parallel: Option<bool>

If set to True, the server uses parallel instead of single-threaded execution.

prefetch: Option<bool>

If set to True, the first batch of answers is streamed to the driver even without an explicit request for it.

prefetch_size: Option<u64>

If set, specifies a guideline number of answers that the server should send before the driver issues a fresh request.

transaction_timeout: Option<Duration>

If set, specifies a timeout for killing transactions automatically, preventing memory leaks in unclosed transactions.

schema_lock_acquire_timeout: Option<Duration>

If set, specifies how long the driver should wait if opening a transaction is blocked by an exclusive schema write lock.

read_any_replica: Option<bool>

If set to True, enables reading data from any replica, potentially boosting read throughput. Only settable in TypeDB Cloud.

Implementations
