@Internal

extends Object

JVM Cache that can be cleared without blocking.

Unlike normal JvmCache, this cache will not block when it is cleared while a value is being generated. It has the following properties:

• At most one thread can generate value for a key concurrently.
• Generated value will be returned to the current thread even if the cache was cleared during the value generation.
