Multiple Query Blocks

Often we want to be able to run multiple query blocks in a single round trip to maximize latency.

The db.ExecuteQueries() function accepts a list of QueryBuilder and it will smartly compose a single giant query to be sent to DGraph.

var data1 []map[string]interface{}

query1 := db.
    Query(dqlx.HasFn("name")).
    Select(`
        uid
        name
        species
    `).
    Filter(
        dqlx.EqFn("name", "Ollie"),
    ).
    UnmarshallInto(&data1)

var data2 []map[string]interface{}

query2 := db.
    Query(dqlx.HasFn("name")).
    Select(`
        uid
        name
        species
    `).
    Filter(
        dqlx.EqFn("name", "Leo"),
    ).
    UnmarshallInto(&data2)

resp, err := db.ExecuteQueries(ctx, []dqlx.QueryBuilder{query1, query2})
