com.trivago.triava.tcache.storage.HighscalelibNonBlockingHashMap<K,V>

Type Parameters:

K - The key class

V - The value class

All Implemented Interfaces:

StorageBackend<K,V>

public class HighscalelibNonBlockingHashMap<K,V>
extends Object
implements StorageBackend<K,V>

Implements a storage that uses the Highscale libs. It is only implemented for performance tests. The instantiation is done fully via reflection, for avoiding compile-time dependencies to 3rd-party libraries.

                                                  double evictionMapSizeFactor)

Description copied from interface: StorageBackend

Returns a ConcurrentMap conforming to the configuration specified in the builder. The sizeFactor is a hint that the Map should be sized bigger due to the Cache implementation. For example if eviction starts at 95% fill rate, sizeFactor could be 1 - 1/0.95 = 0,0526316

Specified by:

createMap in interface StorageBackend<K,V>

Parameters:

builder - The configuration parameter for the Map

evictionMapSizeFactor - Sizing factor to take into account

Returns:

An instance of the storage.
