a leveldb wrapper for levigo

simplify use leveldb in go

Install

download leveldb and snappy source, uncompress and set source directory in build_deps.sh
. ./build_deps.sh

Performance

for better performance, I change some leveldb configurations to build:

db/dbformat.h

  // static const int kL0_SlowdownWritesTrigger = 8;
  static const int kL0_SlowdownWritesTrigger = 16;

  // static const int kL0_StopWritesTrigger = 12;
  static const int kL0_StopWritesTrigger = 64;

db/version_set.cc

  //static const int kTargetFileSize = 2 * 1048576;
  static const int kTargetFileSize = 32 * 1048576;

  //static const int64_t kMaxGrandParentOverlapBytes = 10 * kTargetFileSize;
  static const int64_t kMaxGrandParentOverlapBytes = 20 * kTargetFileSize;
