Build a PostgreSQL Interface for Miro Data using the CData JDBC Driver

There are a vast number of PostgreSQL clients available on the Internet. From standard Drivers to BI and Analytics tools, PostgreSQL is a popular interface for data access. Using our JDBC Drivers, you can now create PostgreSQL entry-points that you can connect to from any standard client.

To access Miro data as a PostgreSQL database, use the CData JDBC Driver for Miro and a JDBC foreign data wrapper (FDW). In this article, we compile the FDW, install it, and query Miro data from PostgreSQL Server.

Connect to Miro Data as a JDBC Data Source

To connect to Miro as a JDBC data source, you will need the following:

• Driver JAR path: The JAR is located in the lib subfolder of the installation directory.

• Driver class:

  cdata.jdbc.api.APIDriver
  

• JDBC URL: The URL must start with "jdbc:api:" and can include any of the connection properties in name-value pairs separated with semicolons.

  Using API Key Authentication

  Miro uses API Key authentication with an access token. To generate an access token:

  1. Log in to your Miro account
  2. Navigate to Settings > Your apps
  3. Click "Create new app" or select an existing app
  4. Configure the required permissions (e.g., boards:read, teams:read)
  5. Install the app and generate an access token
  6. Copy the generated access token (it will only be shown once)

  After obtaining your access token, set the following connection properties:

  • AuthScheme: Set this to APIKey.
  • APIKey: Set this to your access token.

  Connecting to Miro

  Once the authentication is configured, you can connect to Miro and query data from any of the available tables such as Boards, Items, Teams, Organizations, and more.

  Built-in Connection String Designer

  For assistance in constructing the JDBC URL, use the connection string designer built into the Miro JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

  java -jar cdata.jdbc.api.jar
  

  Fill in the connection properties and copy the connection string to the clipboard.

  

  A typical JDBC URL is below:

  jdbc:api:Profile=C:\profiles\Miro.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_access_token';
  

Build the JDBC Foreign Data Wrapper

The Foreign Data Wrapper can be installed as an extension to PostgreSQL, without recompiling PostgreSQL. The jdbc2_fdw extension is used as an example (downloadable here).

1. Add a symlink from the shared object for your version of the JRE to /usr/lib/libjvm.so. For example:

   ln -s /usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server/libjvm.so /usr/lib/libjvm.so
   

2. Start the build:

   make install USE_PGXS=1
   

Query Miro Data as a PostgreSQL Database

After you have installed the extension, follow the steps below to start executing queries to Miro data:

1. Log into your database.
2. Load the extension for the database:

   CREATE EXTENSION jdbc2_fdw;
   

3. Create a server object for Miro:

   CREATE SERVER API 
   FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS (
   drivername 'cdata.jdbc.api.APIDriver',
   url 'jdbc:api:Profile=C:\profiles\Miro.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_access_token';',
   querytimeout '15',
   jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.api.jar'); 
   

4. Create a user mapping for the username and password of a user known to the MySQL daemon.

   CREATE USER MAPPING for postgres SERVER API OPTIONS (
   username 'admin', 
   password 'test');
   

5. Create a foreign table in your local database:

   postgres=# CREATE FOREIGN TABLE boards (
   boards_id text,
   boards_ text,
   boards_ numeric) 
   SERVER API OPTIONS (
   table_name 'boards');
   

postgres=# SELECT * FROM boards;
