Classes in org.apache.hadoop.hbase.io.hfile that implement BlockCache

Modifier and Type	Class and Description
class	CombinedBlockCache CombinedBlockCache is an abstraction layer that combines LruBlockCache and BucketCache.
class	InclusiveCombinedBlockCache
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(org.apache.hadoop.hbase.io.hfile.BlockCacheKey, org.apache.hadoop.hbase.io.hfile.Cacheable, boolean) and LruBlockCache.getBlock(org.apache.hadoop.hbase.io.hfile.BlockCacheKey, boolean, boolean, boolean) operations.
class	MemcachedBlockCache Class to store blocks into memcached.

Modifier and Type	Method and Description
static BlockCacheUtil.CachedBlocksByFile	BlockCacheUtil.getLoadedCachedBlocksByFile(org.apache.hadoop.conf.Configuration conf, BlockCache bc) Get a BlockCacheUtil.CachedBlocksByFile instance and load it up by iterating content in BlockCache.
void	LruBlockCache.setVictimCache(BlockCache handler)
static boolean	BlockCacheUtil.shouldReplaceExistingCacheBlock(BlockCache blockCache, BlockCacheKey cacheKey, Cacheable newBlock) Because of the region splitting, it's possible that the split key locate in the middle of a block.
static String	BlockCacheUtil.toJSON(BlockCache bc)
