auto build index strategy

Fields

policy_type: Option<AutoBuildPolicyType>

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.

timing: String

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.

period_in_second: u64

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

row_count_increment: u64

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

row_count_increment_ratio: f64

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