Commit Message

Add Hazelcast to the analysis suite

Hazelcast does not honor the maximum size and instead performs an
eviction at periodic time intervals. In order to evaluate the hit
rate, the internal data structures are used to trigger an eviction
if the cache exceeds the maximum.

This cache has a concurrent throughput of 22k reads/s and 28k
writes/s. From glancing at the implementation, this is likely due
to the statistics. Those cannot be disabled and would thrash on an
atomic counter increment. It may be switching to a LongAdder-based
counter would make reads competitive.

The single threaded eviction rate ranges from 115k - 430k ops/s. The
hit rate differs from the samples lfu, lru, random policies due to
their sampling approach (a lazy iteration rather than uniform). The
difference is sometimes in their favor, sometimes not, but stays
within expectations that classic policies will under perform.
