GET Command

The GET command is used to download files from a Lakehouse Volume object to the client's local path. It supports three source types: external Volume, TABLE VOLUME, and USER VOLUME.

Execution Methods

GET is a client-side command; the Lakehouse client tool receives the data and writes it to the local file system. The following execution methods are supported:

Syntax

GET { VOLUME volume_name | TABLE VOLUME table_name | USER VOLUME } [ FILE 'file' ] TO 'local_path' [ option_key = option_value ] ...

Parameter Description

ParameterRequiredDescription
VOLUME volume_nameOne of threeDownload files from the specified external Volume.
TABLE VOLUME table_nameOne of threeDownload files from the staging space of the specified table's TABLE VOLUME.
USER VOLUMEOne of threeDownload files from the current user's USER VOLUME.
FILE 'file'NoSpecifies the file path to download (relative to the Volume root). If not specified, all files under the Volume root are downloaded.
local_pathYesLocal destination path. Linux/macOS paths start with /; Windows uses forward slashes as separators.

Examples

Example 1: Download a Specific File from USER VOLUME

GET USER VOLUME FILE 'university_info.csv' TO '/Users/Downloads/';

Example 2: Download a File from a Subdirectory of USER VOLUME

GET USER VOLUME FILE 'test_export/part00001.csv' TO '/Users/Downloads/output/';

Example 3: Download a File from an External Volume

GET VOLUME hz_image_volume FILE 'catsdogs.zip' TO '/Users/Downloads/';

Example 4: Export Table Data and Download Locally

First export the table data to USER VOLUME, then download it locally:

-- Export table data to a USER VOLUME subdirectory COPY INTO USER VOLUME SUBDIRECTORY 'tmp/' FROM TABLE mytable FILE_FORMAT = (TYPE = CSV); -- View the exported files SHOW USER VOLUME DIRECTORY;

+---------------------------+------+---------------------+ | relative_path | size | last_modified_time | +---------------------------+------+---------------------+ | tmp/part00001.csv | 61 | 2026-05-09 06:34:53 | +---------------------------+------+---------------------+

-- Download the file locally GET USER VOLUME FILE 'tmp/part00001.csv' TO '/Users/Downloads/'; -- Delete the temporary file from the Volume after downloading REMOVE USER VOLUME FILE 'tmp/part00001.csv';

Notes

  • Downloading files from an external Volume incurs object storage download fees for the associated cloud account.
  • Executing the GET command requires read permission on the source Volume.
  • The directory specified by local_path must already exist on the client's local file system; the command does not create directories automatically.
  • When downloading large files, network bandwidth and local disk space are the primary limiting factors. Confirm available space beforehand.
