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 |
TinyLfuBlockCache
A block cache that is memory-aware using
HeapSize , memory bounded using the W-TinyLFU
eviction algorithm, and concurrent. |
