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

&self,
selector_key: SelectorResultKey,
result: Arc<SelectorResultValue>,
)
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.
Sourcepub fn write_cache(&self) -> Option<&Arc<WriteCache>>
pub fn write_cache(&self) -> Option<&Arc<WriteCache>>
Calls CacheManager::write_cache(). It returns None if the strategy is CacheStrategy::Disabled.

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