Apache Ignite, Scan Query without filter and Iterator over cache, both returns empty result set. The number of entries in the cache is non-zero - ignite

Question

Apache Ignite Version: 2.8.0
While starting the first ignite cache node, below code snippets, give expected output. When the second ignite cache joins the cluster, the entries object in the first code snippet is empty while in the second snippet iter.hasNext() gives false.
The ignite cluster is started with ShareNothing persistance.
Cache mode is set to CacheMode.REPLICATED.
Both the nodes are in server mode.
call to size() in both instances give a non-zero value.
call to localSize() gives non-zero value in the first instance, but 0 in second instance.
Map results = new HashMap();
QueryCursor<Cache.Entry> entries = binaryCache.query(new ScanQuery(null));
logger.log(Level.DEBUG, "CacheSize from entrySet: [%s]", binaryCache.size()); // Outputs non zero number.
try {
for (Cache.Entry e : entries) {
results.put(e.getKey(), e.getValue());
}
} catch (IOException e) {
throw new RuntimeException("Error deserializing ignite entry", e);
}
return results.entrySet();
OR
Map results = new HashMap();
Iterator<Cache.Entry<Object, BinaryObject>> iter = binaryCache.iterator();
logger.log(Level.DEBUG, "CacheSize from entrySet: [%s]", binaryCache.size()); // Outputs non zero number.
try {
while(iter.hasNext()) {
Cache.Entry e = iter.next();
results.put(e.getKey(), e.getValue());
}
} catch (IOException e) {
throw new RuntimeException("Error deserializing ignite entry", e);
}
return results.entrySet();
As null is passed to ScanQuery, ideally, all the entries from the cache should be fetched.

Answer 1

IgniteCache is iterable, as you noticed in the second example.
If you need to get the stored values, the simplest code would be like:
IgniteCache<Object, BinaryObject> myCache = ignite.getOrCreateCache(ccfg).withKeepBinary();
for(Cache.Entry<Object, BinaryObject> entry: myCache){
System.out.println(entry.getKey() + " " + entry.getValue());
}
System.out.println("trying again");
for(Cache.Entry<Object, BinaryObject> entry: myCache){
System.out.println(entry.getKey() + " " + entry.getValue());
}

Answer 2

If cache has cache store, it may desync since cache store loads are not propagated across cluster. This is how cache store works on replicated caches.
