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().

Summary: Improve the internal interface between java and c++ for basic db operations by including the RocksDB native handle (i.e., c++ pointer of rocksdb::DB) as a input parameter of the internal interface. This improvement reduces one JNI call per db operation from c++.

[JNI] Add java api and java tests for WriteBatch and WriteOptions, add put() and remove() to RocksDB. Summary: * Add java api for rocksdb::WriteBatch and rocksdb::WriteOptions, which are necessary components for running benchmark. * Add java test for org.rocksdb.WriteBatch and org.rocksdb.WriteOptions. * Add remove() to org.rocksdb.RocksDB, and add put() and remove() to RocksDB which take org.rocksdb.WriteOptions.

Summary: This diff contains a simple jni library for rocksdb which supports open, get, put and closeusing default options (including Options, ReadOptions, and WriteOptions.) In the usual case, Java developers can use the c++ rocksdb library in the way similar to the following: RocksDB db = RocksDB.open(path_to_db); ... db.put("hello".getBytes(), "world".getBytes(); byte[] value = db.get("hello".getBytes()); ... db.close(); Specifically, this diff has the following major classes: * RocksDB: a Java wrapper class which forwards the operations from the java side to c++ rocksdb library. * RocksDBException: ncapsulates the error of an operation. This exception type is used to describe an internal error from the c++ rocksdb library. This diff also include a simple java sample code calling c++ rocksdb library. To build the rocksdb jni library, simply run make jni, and make jtest will try to build and run the sample code. Note that if the rocksdb is not built with the default glibc that Java uses, java will try to load the wrong glibc during the run time. As a result, the sample code might not work properly during the run time. Test Plan: * make jni * make jtest Reviewers: haobo, dhruba, sdong, igor, ljin Reviewed By: dhruba CC: leveldb, xjin Differential Revision: https://reviews.facebook.net/D17109
