Summary: * Add a benchmark for java binding for rocksdb. The java benchmark is a complete rewrite based on the c++ db/db_bench.cc and the DbBenchmark in dain's java leveldb. * Support multithreading. * 'readseq' is currently not supported as it requires RocksDB Iterator. * usage: --benchmarks Comma-separated list of operations to run in the specified order Actual benchmarks: fillseq -- write N values in sequential key order in async mode fillrandom -- write N values in random key order in async mode fillbatch -- write N/1000 batch where each batch has 1000 values in random key order in sync mode fillsync -- write N/100 values in random key order in sync mode fill100K -- write N/1000 100K values in random order in async mode readseq -- read N times sequentially readrandom -- read N times in random order readhot -- read N times in random order from 1% section of DB Meta Operations: delete -- delete DB DEFAULT: [fillseq, readrandom, fillrandom] --compression_ratio Arrange to generate values that shrink to this fraction of their original size after compression DEFAULT: 0.5 --use_existing_db If true, do not destroy the existing database. If you set this flag and also specify a benchmark that wants a fresh database, that benchmark will fail. DEFAULT: false --num Number of key/values to place in database. DEFAULT: 1000000 --threads Number of concurrent threads to run. DEFAULT: 1 --reads Number of read operations to do. If negative, do --nums reads. --key_size The size of each key in bytes. DEFAULT: 16 --value_size The size of each value in bytes. DEFAULT: 100 --write_buffer_size Number of bytes to buffer in memtable before compacting (initialized to default value by 'main'.) DEFAULT: 4194304 --cache_size Number of bytes to use as a cache of uncompressed data. Negative means use default settings. DEFAULT: -1 --seed Seed base for random number generators. DEFAULT: 0 --db Use the db with the following name. DEFAULT: /tmp/rocksdbjni-bench * Add RocksDB.write().
