Stage

Using the Cloud Portal

Using the Management API

Use the Stage path (/v1/stage endpoint) in the Management API to manage files and folders in a Stage. Refer to Management API and Management API Reference for more information.

For example, the following API call lists all the files and folders in the Stage attached to the workspace group with the specified ID:

curl -X 'GET' \  'https://api.singlestore.com/v1/stage/68af2f46-0000-1000-9000-3f6f5365d878/fs/' \
  -H 'accept: application/json'

Using Notebooks or SingleStore Python Client

The SingleStore Python SDK supports the Stage object, which can be used to manage files and folders in a Stage. You can also use the Stage object (including other objects in the SingleStore Python SDK) in a Notebook. Refer to the SingleStore Python Client and SingleStore Python SDK API Reference for more information.

For example, the following code snippet uploads a file named data.csv to a Stage attached to a workspace group named examplewsg:

from singlestoredb import manage_workspaces
 
mgr = manage_workspaces('access_key_token_for_the_Management_API')
wg = mgr.workspace_groups['examplewsg']
wg.stage.upload_file('/filepath/data.csv', '/data.csv')

Using the Cloud Portal

1. Under Stage, select the ellipsis (three dots) in the Actions column of the file to upload, and then select Load To Database.

2. In the Load Data dialog, from the Choose Workspace list, select a workspace.

3. From the Choose a database list, select a database.

4. In the Table box, select an existing table or enter a new table name.

5. Select the Generate Notebook button. A notebook is created, which shows the breakdown of all the queries that may be loaded with the notebook.

   You may edit the queries in the notebook to include different column names, column types, etc.

6. Select Run > Run All Cells.

7. Run the Check that the data has loaded cell to verify the loaded data.

Using Pipelines

Create a table with a structure that can store the data from the file. Use the following CREATE PIPELINE syntax to load a file from a Stage:

CREATE PIPELINE <pipeline_name>
AS LOAD DATA STAGE <path_in_Stage/filename> { <pipeline_options> }
INTO TABLE <table_name>
{ <data_format_options> }

Once the table and pipeline are created, start the pipeline. Refer to CREATE PIPELINE for the complete syntax and related information.

Here's a sample CREATE PIPELINE statement that loads data from a CSV file:

CREATE PIPELINE dbTest.plTest
AS LOAD DATA STAGE 'data.csv'
BATCH_INTERVAL 2500
SKIP DUPLICATE KEY ERRORS
INTO TABLE t1
FIELDS TERMINATED BY ',' ENCLOSED BY '"' ESCAPED BY '\\' 
LINES TERMINATED BY '\n' STARTING BY '' 
FORMAT CSV;
