CREATE STREAMLIT

Creates a new Streamlit application object in Snowflake or replaces an existing Streamlit application object in the same schema.

See also:

SHOW STREAMLITS, DESCRIBE STREAMLIT, ALTER STREAMLIT, DROP STREAMLIT

Syntax

CREATE [ OR REPLACE ] STREAMLIT [ IF NOT EXISTS ] <name>
  FROM <source_location>
  MAIN_FILE = '<path_to_main_file_in_root_directory>'
  QUERY_WAREHOUSE = <warehouse_name>
  [ COMMENT = '<string_literal>' ]
  [ TITLE = '<app_title>' ]
  [ IMPORTS = ( '<stage_path_and_file_name_to_read>' [ , ... ] ) ]
  [ EXTERNAL_ACCESS_INTEGRATIONS = ( <integration_name> [ , ... ] ) ]
  [ ROOT_LOCATION = '<stage_path_and_root_directory>' ]
Copy

Required parameters

name

Specifies the identifier (i.e. name) for the Streamlit object. This identifier must be unique for the schema in which the table is created.

In addition, the identifier must start with an alphabetic character and cannot contain spaces or special characters unless the entire identifier string is enclosed in double quotes (e.g. "My object"). Identifiers enclosed in double quotes are also case-sensitive.

For more details, see Identifier requirements.

FROM source_location

Copies the source files from the specified location to initialize the app. This happens once. For example, FROM @streamlit_db.streamlit_schema.streamlit_stage.

MAIN_FILE = 'path_to_main_file_in_root_directory'

Specifies the filename of the Streamlit Python application. This filename is relative to the value of ROOT_LOCATION.

QUERY_WAREHOUSE = warehouse_name

Specifies the warehouse to run SQL queries issued by the Streamlit application.

Note

If you’re creating or replacing a Streamlit application object within the Snowflake Native App Framework, the QUERY_WAREHOUSE parameter is optional.

Optional parameters

COMMENT = 'string_literal'

Specifies a comment for the Streamlit object.

DEFAULT: No value

TITLE = 'app_title'

Specifies a title for the Streamlit app to display in Snowsight.

IMPORTS = ( 'stage_path_and_file_name_to_read' [ , ... ] )

The location (stage), path, and name of the file(s) to import.

EXTERNAL_ACCESS_INTEGRATIONS = ( integration_name [ , ... ] )

The names of external access integrations needed in order for the Streamlit app code to access external networks.

ROOT_LOCATION = 'stage_path_and_root_directory'

Important

ROOT_LOCATION is a legacy parameter. Snowflake recommends using FROM source_location.

For Streamlit apps created using ROOT_LOCATION, multi-file editing and Git integration are not supported.

Specifies the full path to the named stage containing the Streamlit Python files, media files, and the environment.yml file, for example:

ROOT_LOCATION = '@streamlit_db.streamlit_schema.streamlit_stage'
Copy

In this example, the Streamlit files are located on a named stage named streamlit_stage within a database named streamlit_db and schema named streamlit_schema.

Note

  • This parameter must point to a single directory inside a named internal stage.

  • External stages are not supported for Streamlit in Snowflake.

  • If you’re creating or replacing a Streamlit application object within the Snowflake Native App Framework, use FROM 'relative_path_from_stage_root_directory' and not ROOT_LOCATION = 'stage_path_and_root_directory'.

Usage notes

  • When you clone a schema or database containing a Streamlit object, the Streamlit object is not cloned.

  • To specify the packages used by the Streamlit application, use an environment.yml file.

  • Regarding metadata:

    Attention

    Customers should ensure that no personal data (other than for a User object), sensitive data, export-controlled data, or other regulated data is entered as metadata when using the Snowflake service. For more information, see Metadata fields in Snowflake.

  • The OR REPLACE and IF NOT EXISTS clauses are mutually exclusive. They can’t both be used in the same statement.

  • CREATE OR REPLACE <object> statements are atomic. That is, when an object is replaced, the old object is deleted and the new object is created in a single transaction.

Examples

To create a Streamlit app from a stage, run the CREATE STREAMLIT command, as shown in the following example:

CREATE STREAMLIT hello_streamlit
  FROM @streamlit_db.streamlit_schema.streamlit_stage
  MAIN_FILE = 'streamlit_main.py'
  QUERY_WAREHOUSE = my_warehouse;
Copy

To create a Streamlit app from a Git repository, run the CREATE STREAMLIT command, as shown in the following example:

CREATE STREAMLIT hello_streamlit
  FROM @streamlit_db.streamlit_schema.streamlit_repo/branches/streamlit_branch/
  MAIN_FILE = 'streamlit_main.py'
  QUERY_WAREHOUSE = my_warehouse;
Copy
