Spark Writersupports configuring Spark partition，more numerous partitions allow work to be distributed among more workers, however, fewer partitions allow work to be done in larger chunks (and often quicker). #1412
- NebulaGraph Studio is the graphical user interface for working with Nebula. Query, visualize nebula and import CSV data to Nebula. Visualize and explore graph data via the interface; an editor with syntax highlighting feature enables users to design queries fast and view query results in a structured manner; support data import via GUI.
