Azure Data Lake Storage Gen2 Support.
As known as abfs
, azdfs
or azdls
.
This service will visist the ABFS URI supported by Azure Data Lake Storage Gen2.
Configuration
root
: Set the work dir for backend.filesystem
: Set the filesystem name for backend.endpoint
: Set the endpoint for backend.account_name
: Set the account_name for backend.account_key
: Set the account_key for backend.
Refer to Builder
’s public API docs for more information.
Environment
OPENDAL_AZDFS_ROOT
OPENDAL_AZDFS_FILESYSTEM
OPENDAL_AZDFS_ENDPOINT
OPENDAL_AZDFS_ACCOUNT_NAME
OPENDAL_AZDFS_ACCOUNT_KEY
Example
Init OpenDAL Operator
Via Environment
Set environment correctly:
export OPENDAL_AZDFS_ROOT=/path/to/dir/
export OPENDAL_AZDFS_FILESYSTEM=test
export OPENDAL_AZDFS_ENDPOINT=https://accountname.dfs.core.windows.net
export OPENDAL_AZDFS_ACCOUNT_KEY=accountname
export OPENDAL_AZDFS_ACCOUNT_KEY=accountkey

#[tokio::main]
async fn main() -> Result<()> {
let op: Operator = Operator::from_env(Scheme::Azdfs)?;
// Create an object handle to start operation on object.
let _: Object = op.object("test_file");
Ok(())
}

// Set the endpoint, this is required.
//
// For examples:
// - "https://accountname.dfs.core.windows.net"
builder.endpoint("https://accountname.dfs.core.windows.net");
// Set the account_name and account_key.
//
// OpenDAL will try load credential from the env.
// If credential not set and no valid credential in env, OpenDAL will
// send request without signing like anonymous user.
