Hi, in case when you use:
ScanQuery<Long, BinaryObject> scan = new ScanQuery<>((key, value) -> {
System.out.println(key + “ = “ + value);
return true;
})
I think the problem is that you created ScanQuery<Long, BinaryObject> while
your cache is IgniteCache<String, String>. Scan query should be <String,
String> too.
In case of Inner class, it's trying to serialize your outer class, but it
faces some problems in this process. Here you can create separate class
instead of inner, it will help
