This directory contains quick instructions and an example of how to set up fabric
with Neo4j + Helm.

Step 1:  Create custom configmap.

kubectl apply -f deployment-scenarios/fabric/fabric-configmap.yaml

This configmap assumes that in the later step, we're deploying a single instance under
the name "fabric-example".  Note that the virtual fabric database must be on a standalone
instance, not a cluster.

Step 2:  Install a standalone instance using the provided parameters.

helm install fabric-example -f deployment-scenarios/fabric/standalone-fabric.yaml . 

Step 3:  Log in and run Fabric queries!

Run cypher-shell

kubectl run -it --rm cypher-shell \
    --image=neo4j:4.1.0-enterprise \
    --restart=Never \
    --namespace default \
    --command -- ./bin/cypher-shell -u neo4j -p "mySecretPassword" \
    -a neo4j://fabric-example-neo4j.default.svc.cluster.local

Let's create two databases to fabric query, and put a single node in each.

neo4j@system> :use system
neo4j@system> create database shard1;
0 rows available after 297 ms, consumed after another 0 ms
neo4j@system> create database shard2;
0 rows available after 17 ms, consumed after another 0 ms
neo4j@system> :use shard1
neo4j@shard1> create (:Person { name: "David" });
0 rows available after 69 ms, consumed after another 0 ms
Added 1 nodes, Set 1 properties, Added 1 labels
neo4j@shard1> :use shard2
neo4j@shard2> create (:Person { name: "Sarah" });
0 rows available after 33 ms, consumed after another 0 ms
Added 1 nodes, Set 1 properties, Added 1 labels

Finally -- let's run a fabric query!

neo4j@fabric> USE shard1
              MATCH (n) RETURN n
              UNION
              USE shard2
              MATCH (n) RETURN n;
