# MaxCompute configurations

This topic introduces the configuration options for importing data from a MaxCompute data source. For information about the complete configuration file and options, see [Data import configurations](https://dev-docs.nebula-graph.io/v5.3.2/utilities/exchange/config/).

## Data source configurations

The following table lists the configuration options specific to the MaxCompute data source.

 | Option | Description | Type | Required | Default value
 | `type` | The type of the data source. In this case, set the value to `"maxcompute"`. | String | Yes | N/A
 | `table` | The name of the MaxCompute table from which data is retrieved. | String | Yes | N/A
 | `project` | The name of the MaxCompute project. | String | Yes | N/A
 | `odpsUrl` | The URL for accessing MaxCompute. | String | Yes | N/A
 | `tunnelUrl` | The URL for accessing the MaxCompute tunnel service. | String | Yes | N/A
 | `accessKeyId` | The AccessKey ID for accessing MaxCompute. | String | Yes | N/A
 | `accessKeySecret` | The AccessKey Secret for accessing MaxCompute. | String | Yes | N/A
 | `partitionSpec` | The partitions of the MaxCompute table. | String | Yes | N/A
 | `readParallel` | The number of concurrent read requests that are allowed. | Int | No | `32`

## Common source configurations

The following configuration options can also be specified as global settings in the section `sourcesCommon` of the configuration file:

- `type`
- `project`
- `odpsUrl`
- `tunnelUrl`
- `accessKeyId`
- `accessKeySecret`
- `readParallel`

Note that the configurations on specific data sources override the global settings.

## Data source configuration example
