/**
 * ConcurrentSharedMap has very similar semantics as ConcurrentMap with the difference that any updates made to
 * the collections returned from keySet, valueSet and entrySet methods do not change the keys and values in the
 * underlying Map.
 * This is because the Map can contain mutable data such as Buffer and byte[] objects so we must copy such elements
 * before they are returned to you. This prevents a situation where the same entry entry is being updated
 * concurrently by more than one thread, which could lead to race conditions.
