Copy

Arguments

source_path

Source path for copy operation. Can be either stage path or local. You can use a glob pattern for local files but the pattern has to be enclosed in quotes.

destination_path

Target directory path for copy operation. Should be stage if source is local or local if source is stage.

Options

--overwrite / --no-overwrite

Overwrites existing files in the target path. Default: False.

--parallel INTEGER

Number of parallel threads to use when uploading files. Default: 4.

--recursive / --no-recursive

Copy files recursively with directory structure. Default: False.

--auto-compress / --no-auto-compress

Specifies whether Snowflake uses gzip to compress files during upload. Ignored when downloading. Default: False.

--connection, -c, --environment TEXT

Name of the connection, as defined in your config.toml file. Default: default.

--host TEXT

Host address for the connection. Overrides the value specified for the connection.

--port INTEGER

Port for the connection. Overrides the value specified for the connection.

--account, --accountname TEXT

Name assigned to your Snowflake account. Overrides the value specified for the connection.

--user, --username TEXT

Username to connect to Snowflake. Overrides the value specified for the connection.

--password TEXT

Snowflake password. Overrides the value specified for the connection.

--authenticator TEXT

Snowflake authenticator. Overrides the value specified for the connection.

--private-key-file, --private-key-path TEXT

Snowflake private key file path. Overrides the value specified for the connection.

--token-file-path TEXT

Path to file with an OAuth token that should be used when connecting to Snowflake.

--database, --dbname TEXT

Database to use. Overrides the value specified for the connection.

--schema, --schemaname TEXT

Database schema to use. Overrides the value specified for the connection.

--role, --rolename TEXT

Role to use. Overrides the value specified for the connection.

--warehouse TEXT

Warehouse to use. Overrides the value specified for the connection.

--temporary-connection, -x

Uses connection defined with command line parameters, instead of one defined in config. Default: False.

--mfa-passcode TEXT

Token to use for multi-factor authentication (MFA).

--enable-diag

Run Python connector diagnostic test. Default: False.

--diag-log-path TEXT

Diagnostic report path. Default: <temporary_directory>.

--diag-allowlist-path TEXT

Diagnostic report path to optional allowlist.

--format [TABLE|JSON]

Specifies the output format. Default: TABLE.

--verbose, -v

Displays log entries for log levels info and higher. Default: False.

Displays log entries for log levels debug and higher; debug logs contain additional information. Default: False.

--silent

Turns off intermediate output to console. Default: False.

--help

Displays the help text for this command.

Usage notes

  • One of SOURCE_PATH or DESTINATION_PATH must be a local directory, while the other should be a directory in the Snowflake stage. The stage path must start with “@”. For example:

    • snow stage copy @my_stage dir/ - copies files from my_stage stage to the local dir directory.

    • snow stage copy dir/ @my_stage - copies files from the local dir directory to my_stage.

  • You can specify multiple files matching a regular expression by using a glob pattern for the source_path argument. You must enclose the glob pattern in single or double quotes.

Examples

  • To copy files from the local machine to a stage, use a command similar to the following:

    snow stage copy local_example_app @example_app_stage/app
    Copy
    put file:///.../local_example_app/* @example_app_stage/app4 auto_compress=false parallel=4 overwrite=False
+--------------------------------------------------------------------------------------
| source           | target           | source_size | target_size | source_compression...
|------------------+------------------+-------------+-------------+--------------------
| environment.yml  | environment.yml  | 62          | 0           | NONE             ...
| snowflake.yml    | snowflake.yml    | 252         | 0           | NONE             ...
| streamlit_app.py | streamlit_app.py | 109         | 0           | NONE             ...
+--------------------------------------------------------------------------------------

  • To download files from a stage to a local directory, use a command similar to the following:

    mkdir local_app_backup
snow stage copy @example_app_stage/app local_app_backup
    Copy
    get @example_app_stage/app file:///.../local_app_backup/ parallel=4
+------------------------------------------------+
| file             | size | status     | message |
|------------------+------+------------+---------|
| environment.yml  | 62   | DOWNLOADED |         |
| snowflake.yml    | 252  | DOWNLOADED |         |
| streamlit_app.py | 109  | DOWNLOADED |         |

  • The following example copies all .txt files in a directory to a stage.

    snow stage copy "testdir/*.txt" @TEST_STAGE_3
    Copy
    put file:///.../testdir/*.txt @TEST_STAGE_3 auto_compress=false parallel=4 overwrite=False
