9.2.1 Configuring PARALLEL Hint when Loading a Graph
You can also optimize the graph loading performance by configuring a
specific parallel hint value using the GraphConfig field,
PARALLEL_HINT_DEGREE, which will be used by the underlying SQL
queries. This can be applied when loading a graph using a JSON configuration file or
through the GraphConfigBuilder API.
The following table describes how the internal queries are configured based
on the specified PARALLEL_HINT_DEGREE values.
