Yi Wu 30a017feca Blob DB: avoid having a separate read of checksum ... Summary: Previously on a blob db read, we are making a read of the blob value, and then make another read to get CRC checksum. I'm combining the two read into one. readrandom db_bench with 1G database with base db size of 13M, value size 1k: `./db_bench --db=/home/yiwu/tmp/db_bench --use_blob_db --value_size=1024 --num=1000000 --benchmarks=readrandom --use_existing_db --cache_size=32000000` master: throughput 234MB/s, get micros p50 5.984 p95 9.998 p99 20.817 p100 787 this PR: throughput 261MB/s, get micros p50 5.157 p95 9.928 p99 20.724 p100 190 Closes https://github.com/facebook/rocksdb/pull/3301 Differential Revision: D6615950 Pulled By: yiwu-arbug fbshipit-source-id: 052410c6d8539ec0cc305d53793bbc8f3616baa3		7 years ago
