Is Caching of type List<Map<String, Object> thread safe?

[jbleeok]

If have a cache definition as below. Will it thread safe? It looks working.
static Cache<String, List<Map<String, Object> cacheList = Caffeine.newBuilder().build();
TIA

Yes, this cache library is thread safe

Great!!!
Thank you for the answer.

Node that if you need to do complex operations on the value, that may not be thread-safe. So for example cacheList.get(key).add(Map.of()) would make a thread-safe call to the cache, but mutating the List may not be (e.g. if an ArrayList). Typically one treats a cache's value as immutable. If you do need to do complex operations, then you might use an asMap() compute method or a copy-on-write data structure (e.g. CopyOnWriteArrayList). This library is thread-safe but your usages may not be, so be thoughtful about concurrent reads when mutating a value.
