Add new data in Redis memory

[sandeepsajan0]

Every time when I am trying to add some more data to Redis memory or update the Redis graph, I get the unwanted result like double of previous data means previous_data + (previous_data + new_data) but I want to add only new data.

Some different solutions suggested by @Mec-iS

• Build a secondary index using a Redis Set

• use hashing on objects, and store only the first x characters

• Some Redis commands have the "NX" suffix to ensure that a key or a member is created only if does
  not exist

and

In general, this is an "upsert" problem that can be solved with transactions (see MULTI EXEC and    WATCH commands in Redis)`

@Mec-iS @xadahiya As you suggest the things regarding the solution, I have read about it. But I can not understand how I can use these solutions to Redis graph.
Ex. of problem:
we add a node and commit it with redis_graph(connection).
node1 = Node( "collection", endpoint, node_properties)
redis_graph.add_Node(node)
redis_graph.commit()
then redis_graph have an node with label ="collection" and alias = endpoint and properties as node_properties
Now, if we add 1 more node to the same graph(redis_graph) like this:
node2 = Node( "objects", endpoint1, node_properties1)
redis_graph.add_node(node2)
redis_graph.commit()
Now we expects that we would have 2 nodes in graph but when we access the node of graph there are three nodes 2 identical nodes for node1 and 1 node for node2.
It occurs because when we have committed the graph second time then it has two nodes node1 and node2 while node1 is already committed. So, node1 committed 2 times.

And I am unable to use some Redis command like NX with Redis graph command like redis_graph.commit(). So, please tell me how I can handle now.
