Getting Started

New User Registration and Organization Creation

User Login

VeloDB Cloud supports a login-as-registration scheme. Registration is done the first time you log in with a verification code. Registered users can log in with a verification code or a password.

Click (opens in a new tab) to enter the VeloDB Cloud login page.

Create Organization

Organization is the billing unit. Each organization will be billed individually. We recommend that you divide organizations by cost unit, and one user can be affiliated to multiple organizations. Multiple warehouses can be created under one organization.

If you haven't been a member of any organizations, after login, you will see a wizard page about how to create your first organization.

Change Password

After login, click User Menu > Profile to change the login password for the VeloDB Cloud console.

Once you have successfully changed the password for the first time, you can use the password for subsequent logins.

Warehouse and Cluster Creation

In VeloDB Cloud, the warehouse is a logical concept that includes physical objects such as warehouse metadata, clusters, and data storage.

Under each organization, you can create multiple warehouses to meet the needs of different business systems, and the resources and data between these warehouses are isolated.

Create Warehouse

A wizard page will be displayed if the organization does not have a warehouse. You can create the first warehouse following the prompts.

You can choose to Activate Trial Warehouse for a free trial. Each organization gets a 7-day free trial.

Create Cluster

If you have activated the trial warehouse, you will see a trial cluster in that warehouse.

In the trial warehouse, you may try the features by importing small amounts of data. You may not create paid clusters under the trial warehouse. If you are happy with the trial experience, you can upgrade the trial warehouse to a paid one, and then you can create paid clusters under the paid warehouse.

Change Warehouse Password

The username and password are required when connecting to a warehouse. VeloDB Cloud initializes the username ('admin') and password for you. You can change the password on the Settings page.

Warning The password only supports uppercase letters, lowercase letters, numbers and special characters ~!@#$%^&*()_+|&lt&gt,.?/:;'[]", need to contain at least 3 of them, length 8-20 characters.

Connect to Warehouse Using WebUI

Click WebUI in the left navigation bar, open the login page, enter the username and password, and enter the WebUI interface after completing the login.

Create Database

Execute the following statement in the query editor:

create database demo;

Create Data Table

Execute the following statement in the query editor:

use demo;
create table mytable
k2 DECIMAL(10, 2) DEFAULT "10.05",
k3 CHAR(10) COMMENT "string column",
k4 INT NOT NULL DEFAULT "1" COMMENT "int column"
COMMENT "my first table"

You can see the fields of mytable through desc mytable.

Insert Data

Execute the following statement in the query editor:

INSERT INTO mytable (k1, k2, k3, k4) VALUES
(1, 0.14, 'a1', 20),
(2, 1.04, 'b2', 21),
(3, 3.14, 'c3', 22),
(4, 4.35, 'd4', 23);

Query Data

The table creation and data import are completed above, and the query can be performed below.

select * from mytable;

(OPTIONAL)Connect to Warehouse Using MySQL Client

IP Whitelist Management

On the Connections page, switch to the Public Link tab to manage IP whitelist. Click Add IP Whitelist to add new IP addresses.

In the IP whitelist, users can add or delete IP addresses to enable or disable their access to the warehouse.

MySQL Client

You may download MySQL Client from the official website of MySQL. Here we provide a Linux-free version of MySQL Client (opens in a new tab). If you need MySQL Client for Mac and Windows, please go to the MySQL official website.

Currently, VeloDB is compatible with MySQL Client 5.7 and above.

You may read details about connections by clicking "Connections" on the target warehouse on the VeloDB Cloud console.


  1. The warehouse supports public network connection and private network (PrivateLink) connection. Different connection methods require different connection information.

  2. The public network connection is open by default, and the IP whitelist is also open to the public by default. If you no longer need to connect to the warehouse from the public network, please close it.

  3. For the first connection, please use the user admin and its password. You can initialize or reset it in the Setting page on VeloDB Cloud console.

Supposing that you are connecting to a warehouse using the following public link:

Download MySQL Client and unzip the file, find the mysql command line tool under the bin/ directory. Execute the folowing command to connect to VeloDB.

mysql -h -P 33641 -u admin -p

After login, if you see the following snippet, that usually means that your Client IP address has not been added to the connection whitelist on the console.

ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 2

If the following is displayed, that means the connection succeeds.

Create Database and Table

Create Database

create database demo;

Create Table

use demo;
create table mytable
    k1 TINYINT,
    k2 DECIMAL(10, 2) DEFAULT "10.05",
    k3 CHAR(10) COMMENT "string column",
    k4 INT NOT NULL DEFAULT "1" COMMENT "int column"
COMMENT "my first table"

You may check details of mytable via desc mytable.

Load Data

Save the following sample data in the local data.csv:


Upload data via HTTP protocol:

curl -u admin:admin_123 -H "fileName:dir1/data.csv" -T data.csv -L ''

You can call and upload multiple files be repeating this command.

Load data by the copy into command:

curl -u admin:admin_123 -H "Content-Type: application/json" '' -d '{"sql": "copy into demo.mytable from @~(\"dir1/data.csv\") PROPERTIES (\"file.column_separator\"=\",\", \"copy.async\"=\"false\")"}'

dir1/data.csv refers to the file uploaded in the previous step. Wildcard and glob pattern matching are supported here.

The service side can automatically identify general formats such as csv.

file.column_separator="," specifies comma as the separator in the csv format。

Since the copy into command is submitted asychronously by default, "copy.async"="false" is specified here to implement synchronous submission. That is, the command will only return after the data are loaded successfully.

If you see the following response, that means the data are successfully loaded.

    "msg": "success",
    "code": 0,
    "data": {
        "result": {
            "msg": "",
            "loadedRows": "4",
            "id": "d33e62f655c4a1a-9827d5561adfb93d",
            "state": "FINISHED",
            "type": "",
            "filterRows": "0",
            "unselectRows": "0",
            "url": null
        "time": 5007,
        "type": "result_set"
    "count": 0

Query Data

After table creation and data loading, you may execute queries on the data.
