Watch updates in redis graph

I've recently discovered that redis has a property graph model implementation called redis graph and it's amazing.

One thing that I really miss for my use-case though, is the ability to "watch" the data. In typical redis data structures I can enable Keyspace notifications or client tracking and be notified on the data mutations I'm interested in, pull data from the server or mark my local cache as "dirty".

I don't know how that would work for a property graph since relations are much more complex (and the key feature for that matter), but is there a way to watch or synchronize with data stored in redis graph?

Solution

Keyspace notifications can be enabled for modules like this:

redis.cloud> CONFIG SET notify-keyspace-events AKE

The 'A' part includes modules—if the module publishes anything. Unfortunately, I tried this with RedisGraph, and it doesn't.

You can reproduce my test below. In one terminal I launched redis-cli and did this:

127.0.0.1:6379> PSUBSCRIBE *
Reading messages... (press Ctrl-C to quit)
1) "psubscribe"
2) "*"
3) (integer) 1

In another I did this:

127.0.0.1:6379> GRAPH.QUERY test 'CREATE (n:foo { alfa: 12, bravo: "test" })'
1) 1) "Labels added: 1"
   2) "Nodes created: 1"
   3) "Properties set: 2"
   4) "Cached execution: 0"
   5) "Query internal execution time: 0.204701 milliseconds"
127.0.0.1:6379> GRAPH.QUERY test 'MATCH (n) RETURN n'
1) 1) "n"
2) 1) 1) 1) 1) "id"
            2) (integer) 0
         2) 1) "labels"
            2) 1) "foo"
         3) 1) "properties"
            2) 1) 1) "alfa"
                  2) (integer) 12
               2) 1) "bravo"
                  2) "test"
3) 1) "Cached execution: 0"
   2) "Query internal execution time: 1.106191 milliseconds"
127.0.0.1:6379> GRAPH..DELETE test
"Graph removed, internal execution time: 0.064498 milliseconds"

The first terminal returned nothing in response to this.
