Low-latency in-memory key-value store, Redis drop-in alternative
Ref: `net.openhft.chronicle.map.ChronicleMap`: > Functionally this interface defines some methods supporting garbage-free off-heap programming: getUsing(Object, Object), acquireUsing(Object, Object). Consider using `getUsing` and `accquireUsing`, and `Values.newHeapInstance(byte[].class)`
