title: Can we use Presto to query Oracle Spatial and Graph with PGQL?
body: <p>We will use Oracle Big Data Spatial and Graph. We need to query our distributed graph using PGQL. (The default/given algorithms with PGX are not enough for us.) The graph will use HBase underneath.</p>
  
  <p>The problem is that PGQL only works on a single node of the CDH cluster. You can query a single node at a time but cannot use the entire memory of the cluster. We need a way to query all the nodes, and then aggregate (combine) the results from the nodes and give it to the user.</p>
  
  <p>Is there any way that Presto can help us tackling this problem?</p>
