HBASE-21879 Read HFile ’s Block into ByteBuffer directly. 1. Background For reducing the Java GC impact to p99/p999 RPC latency, HBase 2.x has made an offheap read and write path. The KV are allocated BucketCache firstly, if the Cache misses, go to the HFile and read the corresponding block. The workflow: reading block from cache OR sending cells to client, is basically not involved in heap memory allocations that the process of reading the Block from HFile is still copied to the heap firstly, the heap block won’t free unless the WriterThread of BucketCache flushes the Block to offheap IOEngine successfully
