Solution for hash-map with >100M values
Consider using an database (e.g. H2 embedded, redis) with an on-heap cache (e.g. Caffeine). Since you say it is a Zipfian distribution, the cache should absorb most of the requests. For an off-heap hashtable, you might try Oak as it is likely a faster implementation.
What are some alternatives?
When comparing SmoothieMap and Oak you can also consider the following projects:
java-concurrent-hash-trie-map - Java port of a concurrent trie hash map implementation from the Scala collections library
MapDB - MapDB provides concurrent Maps, Sets and Queues backed by disk storage or off-heap-memory. It is a fast and easy to use embedded Java database engine.
lasher - Lasher is an embeddable key-value store written in Java.
Chronicle Map - Replicate your Key Value Store across your network, with consistency, persistance and performance.
