Ganos allows you to create, import, and export raster data that is stored in Alibaba Cloud Object Storage Service (OSS) buckets, self-managed Multi-Cloud Object Storage (MinIO) buckets, and Hadoop Distributed File System (HDFS) files. This topic describes the paths of the raster data in the buckets and files.

Paths of raster data in OSS buckets

The path of raster data in an OSS bucket is in the following format:
oss://<access_id>:<secrect_key>@[<Endpoint>]/path_to/file[:<subset>]
Note If the raster data is in Network Common Data Form (NetCDF) and contains a subset, you must specify the :<subset> field.

The Endpoint parameter specifies the region where the OSS bucket resides, which is optional. If you do not specify this parameter, Ganos obtains the required endpoint and you must make sure that the path starts with a forward slash (/). To import data at high performance, make sure that your ApsaraDB RDS instance and the OSS bucket reside in the same region. For more information, see OSS domain names.

Paths of raster data in MinIO buckets

The path of raster data in a MinIO bucket is in the following format. For more information about MinIO buckets, see Multi-Cloud Object Storage.
mio://<id>:<key>@<host>[:<port>]/path_to/file[:<subset>]
Note If the raster data is in NetCDF and contains a subset, you must specify the :<subset> field.

If you do not specify the port parameter, the HTTPS port is used. To import data at high performance, make sure that your ApsaraDB RDS instance and the self-managed MinIO bucket reside in the same region and can communicate over an internal network.

Paths of raster data in HDFS files

The path of raster data in an HDFS file is in the following format:
HDFS://<user_name>@<host>:<port>/path_to/file[:<subset>]
Note If the raster data is in NetCDF and contains a subset, you must specify the :<subset> field.
  • If you do not specify the user_name parameter, the default value hadoop is used.
  • The host and port parameters specify the endpoint and port of remote procedure calls (RPCs) in the HDFS configuration file.
  • To import data at high performance, make sure that your ApsaraDB RDS instance and the HDFS cluster reside in the same VPC and communicate over an internal network.
