Connect to SendGrid Data as a Federated Tables in MySQL

Use the CData Cloud Hub to set up federated tables for SendGrid data in MySQL .

You can use the CData Cloud Hub to set up federated tables in MySQL for SendGrid data. The Cloud Hub provides a MySQL interface for SendGrid: After configuring a virtual MySQL database for SendGrid, you can create a server and tables using the FEDERATED Storage Engine in MySQL. You can then work with SendGrid data just as you would local MySQL tables.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for SendGrid, allowing you to easily query live SendGrid data alongside existing MySQL data — all without replicating the data. Using optimized data processing out of the box, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to SendGrid, leveraging server-side processing to quickly return SendGrid data.

Create a Virtual MySQL Database for SendGrid Data

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "SendGrid" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to SendGrid.

    To make use of all the available features, provide the User and Password connection properties.

    To connect with limited features, you can set the APIKey connection property instead. See the "Getting Started" chapter of the help documentation for a guide to obtaining the API key.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to SendGrid data from any MySQL client.

Create a FEDERATED Server and Tables for SendGrid Data

After you have configured and started the service, create a FEDERATED server to simplify the process of creating FEDERATED tables:

Create a FEDERATED Server

The following statement will create a FEDERATED server based on the Cloud Hub. Note that the username and password of the FEDERATED server must match a user account you defined on the Cloud Hub.

OPTIONS (USER 'cloud_hub_user', PASSWORD 'cloud_hub_passwd', HOST '', PORT 3306, DATABASE 'sendgriddb');

Create a FEDERATED Table

To create a FEDERATED table using our newly created server, use the CONNECTION keyword and pass the name of the FEDERATED server and the remote table (AdvancedStats). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_advancedstats (
  name  TYPE(LEN),
  clicks  TYPE(LEN),

NOTE: The table schema for the FEDERATED table must match the remote table schema exactly. You can always connect directly to the Cloud Hub using any MySQL client and run SHOW COLUMNS FROM AdvancedStats to get the table schema.

Execute Queries

You can now execute queries to the SendGrid FEDERATED tables from any tool that can connect to MySQL, which is particularly useful if you need to JOIN data from a local table with data from SendGrid. Refer to the following example:

  local_table.foreign_name =;
