Connect to Basecamp Data as a Federated Tables in MySQL

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

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

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Basecamp, allowing you to easily query live Basecamp 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 Basecamp, leveraging server-side processing to quickly return Basecamp data.

Create a Virtual MySQL Database for Basecamp Data

You can use any MySQL client to connect to the CData Cloud Hub and create virtual databases.

  1. Connect to the CData Cloud Hub:
    mysql --host myinstance.cdatacloud.net --user admin --password
    
  2. Once authenticated, create the virtual database for Basecamp:
    mysql> CREATE DATABASE basecampdb
        -> DRIVER = "Basecamp",
        -> DBURL = "User=test@northwind.db;Password=test123;";
    

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

Create a FEDERATED Server and Tables for Basecamp 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.

CREATE SERVER fedBasecamp
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'cloud_hub_user', PASSWORD 'cloud_hub_passwd', HOST 'myinstance.cdatacloud.net', PORT 3306, DATABASE 'basecampdb');

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 (Projects). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_projects (
  ...,
  name  TYPE(LEN),
  documentscount  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=utf8
CONNECTION='fedBasecamp/Projects';

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 Projects to get the table schema.

Execute Queries

You can now execute queries to the Basecamp 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 Basecamp. Refer to the following example:

SELECT 
  fed_projects.name, 
  local_table.custom_field 
FROM 
  local_table 
JOIN 
  fed_projects 
ON 
  local_table.foreign_name = fed_projects.name;
