Deon Nicholas ad48c3c262 Benchmarking for Merge Operator ... Summary: Updated db_bench and utilities/merge_operators.h to allow for dynamic benchmarking of merge operators in db_bench. Added a new test (--benchmarks=mergerandom), which performs a bunch of random Merge() operations over random keys. Also added a "--merge_operator=" flag so that the tester can easily benchmark different merge operators. Currently supports the PutOperator and UInt64Add operator. Support for stringappend or list append may come later. Test Plan: 1. make db_bench 2. Test the PutOperator (simulating Put) as follows: ./db_bench --benchmarks=fillrandom,readrandom,updaterandom,readrandom,mergerandom,readrandom --merge_operator=put --threads=2 3. Test the UInt64AddOperator (simulating numeric addition) similarly: ./db_bench --value_size=8 --benchmarks=fillrandom,readrandom,updaterandom,readrandom,mergerandom,readrandom --merge_operator=uint64add --threads=2 Reviewers: haobo, dhruba, zshao, MarkCallaghan Reviewed By: haobo CC: leveldb Differential Revision: https://reviews.facebook.net/D11535		12 years ago
