§table: String

원본 테이블 이름

§partition_type: PartitionType

파티션 타입

§num_partitions: usize

총 파티션 수

Implementations§

Source§

impl PartitionMap

Source

pub fn route_key(&self, key_value: &PartitionValue) -> String

key 값을 받아 sub-table 이름 반환

반환 형식: {table}__p_part_{idx}

Source

pub fn pruned_partitions( &self, filter_value: Option<&PartitionValue>, ) -> Vec<String>

WHERE 조건값으로 스캔할 파티션 목록 반환 (Pruning)

  • filter_value = None → 모든 파티션 반환 (full scan)
  • filter_value = Some(v) → 해당 v가 속한 파티션만 반환
Source

pub fn all_partitions(&self) -> Vec<String>

모든 파티션의 sub-table 이름 반환

Source

pub fn route_or_expand(&self, key_value: &PartitionValue) -> RouteResult

자동 확장이 필요한지 파악하는 함수
