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, boolean) and LruBlockCache.getBlock(org.apache.hadoop.hbase.io.hfile.BlockCacheKey, boolean, boolean, boolean) operations. |
