Class RocksBenchRead

java.lang.Object

alluxio.inode.RocksBenchRead

public class RocksBenchRead
extends Object

This benchmark measures the performance of RocksDB single key accesses. The keys are InodeIDs and the values are the Inode themselves. The following options can be varied. mUserSerialization - enable or disable ProtoBuf serialization of values. mFileCount - the initial number of inodes stored in RocksDB. mIsDirectory - have the Inodes represent directories or files. mUseZipf - if to use a Zipfian distribution when choosing the keys to read. The more likely keys to be read will be the ones written last, meaning that they will more likely be in the RocksDB memtable. mRocksConfig - see RocksBenchConfig
