// The size amplification is defined as the amount (in percentage) of
// additional storage needed to store a single byte of data in the database.
// For example, a size amplification of 2% means that a database that
// contains 100 bytes of user-data may occupy upto 102 bytes of
// physical storage. By this definition, a fully compacted database has
// a size amplification of 0%. Rocksdb uses the following heuristic
// to calculate size amplification: it assumes that all files excluding
// the earliest file contribute to the size amplification.
// Default: 200, which means that a 100 byte database could require upto
// 300 bytes of storage.
