Uses of BlockCache in org.apache.accumulo.core.file.blockfile.cache.lru

Classes in org.apache.accumulo.core.file.blockfile.cache.lru that implement BlockCache

Modifier and Type	Class	Description
class	LruBlockCache	A block cache implementation that is memory-aware using HeapSize, memory-bound using an LRU eviction algorithm, and concurrent: backed by a ConcurrentHashMap and with a non-blocking eviction thread giving constant-time LruBlockCache.cacheBlock(java.lang.String, byte[], boolean) and LruBlockCache.getBlock(java.lang.String) operations.
class	SynchronousLoadingBlockCache	This class implements loading in such a way that load operations for the same block will not run concurrently.

Methods in org.apache.accumulo.core.file.blockfile.cache.lru that return BlockCache

Modifier and Type	Method	Description
protected BlockCache	LruBlockCacheManager.createCache(BlockCacheManager.Configuration conf, CacheType type)

Uses of BlockCache in org.apache.accumulo.core.file.blockfile.cache.tinylfu
