Enum CacheStrategy

pub enum CacheStrategy {
    EnableAll(CacheManagerRef),
    Compaction(CacheManagerRef),
    Disabled,
}

Cache strategies that may only enable a subset of caches.

Variants

EnableAll(CacheManagerRef)

Strategy for normal operations. Doesn’t disable any cache.

Compaction(CacheManagerRef)

Strategy for compaction. Disables some caches during compaction to avoid affecting queries. Enables the write cache so that the compaction can read files cached in the write cache and write the compacted files back to the write cache.

Disabled

Do not use any cache.

Implementations

impl CacheStrategy

pub async fn get_parquet_meta_data( &self, region_id: RegionId, file_id: FileId, ) -> Option<Arc<ParquetMetaData>>

Calls CacheManager::get_parquet_meta_data().

pub fn get_parquet_meta_data_from_mem_cache( &self, region_id: RegionId, file_id: FileId, ) -> Option<Arc<ParquetMetaData>>

Calls CacheManager::get_parquet_meta_data_from_mem_cache().

pub fn put_parquet_meta_data( &self, region_id: RegionId, file_id: FileId, metadata: Arc<ParquetMetaData>, )

Calls CacheManager::put_parquet_meta_data().

pub fn remove_parquet_meta_data(&self, region_id: RegionId, file_id: FileId)

Calls CacheManager::remove_parquet_meta_data().

pub fn get_repeated_vector( &self, data_type: &ConcreteDataType, value: &Value, ) -> Option<VectorRef>

Calls CacheManager::get_repeated_vector(). It returns None if the strategy is CacheStrategy::Compaction or CacheStrategy::Disabled.

pub fn put_repeated_vector(&self, value: Value, vector: VectorRef)

Calls CacheManager::put_repeated_vector(). It does nothing if the strategy isn’t CacheStrategy::EnableAll.

pub fn get_pages(&self, page_key: &PageKey) -> Option<Arc<PageValue>>

Calls CacheManager::get_pages(). It returns None if the strategy is CacheStrategy::Compaction or CacheStrategy::Disabled.

pub fn put_pages(&self, page_key: PageKey, pages: Arc<PageValue>)

Calls CacheManager::put_pages(). It does nothing if the strategy isn’t CacheStrategy::EnableAll.

pub fn get_selector_result( &self, selector_key: &SelectorResultKey, ) -> Option<Arc<SelectorResultValue>>

Calls CacheManager::get_selector_result(). It returns None if the strategy is CacheStrategy::Compaction or CacheStrategy::Disabled.

pub fn put_selector_result( &self, selector_key: SelectorResultKey, result: Arc<SelectorResultValue>, )

Calls CacheManager::put_selector_result(). It does nothing if the strategy isn’t CacheStrategy::EnableAll.

pub fn write_cache(&self) -> Option<&Arc<WriteCache>>

Calls CacheManager::write_cache(). It returns None if the strategy is CacheStrategy::Disabled.

pub fn inverted_index_cache( &self, ) -> Option<&Arc<IndexCache<FileId, InvertedIndexMetas>>>

Calls [CacheManager::index_cache()]. It returns None if the strategy is CacheStrategy::Compaction or CacheStrategy::Disabled.

pub fn bloom_filter_index_cache( &self, ) -> Option<&Arc<IndexCache<(FileId, ColumnId, Tag), BloomFilterMeta>>>

Calls CacheManager::bloom_filter_index_cache(). It returns None if the strategy is CacheStrategy::Compaction or CacheStrategy::Disabled.

pub fn puffin_metadata_cache(&self) -> Option<&PuffinMetadataCacheRef>

Calls CacheManager::puffin_metadata_cache(). It returns None if the strategy is CacheStrategy::Compaction or CacheStrategy::Disabled.
