Managing HDC Graphs

An HDC graph resides in the memory of an HDC (High-Density Computing) server and contains all or part of the data loaded from a graph, which is physically stored across one or multiple shard servers.

To load the entire current graph onto hdc-server-1 as hdcGraph:

GQLUQL
CREATE HDC GRAPH hdcGraph ON "hdc-server-1" OPTIONS {
  nodes: {"*": ["*"]},
  edges: {"*": ["*"]},
  direction: "undirected",
  load_id: true,
  update: "static"
}

To load account and movie nodes with selected properties and incoming rate edges in the current graph onto hdc-server-1 as hdcGraph_1, while omitting nodes' _id values:

GQLUQL
CREATE HDC GRAPH hdcGraph_1 ON "hdc-server-1" OPTIONS {
  nodes: {
    "account": ["name", "gender"],
    "movie": ["name", "year"]
  },
  edges: {"rate": ["*"]},
  direction: "in",
  load_id: false,
  update: "static"
}
