Apache Ignite - get all from cache

I'm trying to get all items from a Apache Ignite cache.

Currently I can get an individual item using

ClientCache<Integer, BinaryObject> cache = igniteClient.cache("myCache").withKeepBinary();

BinaryObject temp = cache.get(1);

To get all keys, Ive tried the following:

try(QueryCursor<Entry<Integer,BinaryObject>> cursor = cache.query(new ScanQuery<Integer, BinaryObject>(null))) {
    for (Object p : cursor)
        System.out.println(p.toString());
}

This returns a list of org.apache.ignite.internal.client.thin.ClientCacheEntry which is internal, and I cannot call getValue.

How can I get all items for this cache?

Solution

  • By using Iterator you can get all values and key from cache. below are the sample code to retrieve all values from cache.

    Iterator<Entry<Integer, BinaryObject>> itr = cache.iterator();                
while(itr.hasNext()) {
    BinaryObject object = itr.next().getValue();
    System.out.println(object);
}
