I am trying to add support for persistent storage of a feature of an application. So far, I’ve noticed that caches are persisted and retrieved properly, as well as collections (which, from my understanding, is expected as IgniteSet, IgniteQueue are adapters for caches).
However, the IgniteAtomicReferences I use are not found upon restart of the application. I also cannot find any mention of this use-case in the documentation.

Is there no support for persistent atomic types?

Here’s a code snippet similar to the one that creates the IgniteAtomicReference

var ref = Ignition.getOrStart(igniteConfiguration).atomicReference("solve", solve /* guaranteed not null */, true);

// ...
// Then, elsewhere, when I try to retrieve the persisted value after restart:

var hasSolve = ignite.atomicReference("solve", null, false).get() != null; // false

I have enabled persistence on the default data region, as I understand that’s where atomic types are stored.
