Struct AutoBuildPolicyBuilder

pub struct AutoBuildPolicyBuilder { /* private fields */ }

Builder for AutoBuildPolicy.

Implementations

impl AutoBuildPolicyBuilder

pub fn policy_type<VALUE: Into<AutoBuildPolicyType>>( &mut self, value: VALUE, ) -> &mut Self

the policy type of the index: timing: regularly build indexes, only build once, periodical: periodically building indexes, row_count_increment: build index based on new added rows.

pub fn timing<VALUE: Into<String>>(&mut self, value: VALUE) -> &mut Self

time format: LOCAL(%Y-%m-%d %H:%M:%S) and UTC(%Y-%m-%dT%H:%M:%Z), only build once when the policyType is ‘timing’ and it takes effect, When policyType is ‘periodic’, the incoming time serves as the start time of the periodic policy.

pub fn period_in_second<VALUE: Into<u64>>(&mut self, value: VALUE) -> &mut Self

periodInSecond: the interval of periodic building indexes, build index periodically when policyType is ‘periodic’.

pub fn row_count_increment<VALUE: Into<u64>>( &mut self, value: VALUE, ) -> &mut Self

build an index when the number of rows in a tablet increases or decreases by more than rowCountIncrement

pub fn row_count_increment_ratio<VALUE: Into<f64>>( &mut self, value: VALUE, ) -> &mut Self

build index once when the percentage of rows added or decreased by the tablet is greater than rowCountIncrementRatio

pub fn build(&self) -> Result<AutoBuildPolicy, AutoBuildPolicyBuilderError>

Builds a new AutoBuildPolicy.

Errors

If a required field has not been initialized.
