# Flink connector configurations

Configure the NebulaGraph Flink connector with these classes:

- `ConnectionOptions`: used to connect to NebulaGraph Database Developer Edition.
- `SinkNodeOptions`: used to write data to the specified node type in NebulaGraph Database Developer Edition.
- `SinkEdgeOptions`: used to write data to the specified edge type in NebulaGraph Database Developer Edition.
- `SourceExecutionOptions`: used to read data from NebulaGraph Database Developer Edition. It includes two classes: `SourceNodeOptions` and `SourceEdgeOptions`.
