How to connect an external client to an Amazon Revpsheet cluster?
Connecting an external client to a cloud cluster may seem complicated, but with the right steps, you will be able to manage your databases from your personal computer. Let's see how you can accomplish this using Amazon Revpsheet and an external SQL editing program.
What are the necessary configurations in Amazon Revpsheet?
Before establishing a connection to an external client, you must make sure that your Revpsheet cluster is configured to accept external connections:
-
Cluster Access: You should verify in the AWS Management Console that your cluster has the status of "enabled" or "reachable".
-
Allow external connections: In the properties tab, make sure that the flag to receive external connections is set to "yes" or "yes".
-
Configure the firewall rules: Go to the security group of your cluster and adjust the firewall rules to allow connections through Revpsheet's default port, which is 5439. It is recommended to specify which IPs have access for security, although initially you can allow access to any IP for testing.
How to use a SQL client like DB Ever to connect to the cluster?
DB Ever is a lightweight and free SQL editor that can be used on different operating systems (Windows, Linux and MacOS). Here's how to use it to connect to your Revpsheet cluster.
-
Installing DB Ever: If you don't have it installed yet, there are guides available online that will provide you with a step-by-step installation.
-
Create a new connection: In DB Ever, select "new database connection". Select Revpsheet and enter the following details which can be found in the Revpsheet console:
- Host: The address of your cluster host or server.
- Port: 5439.
- Database name: Use the one you assign during cluster creation.
- Username and password: Make sure to use secure and correct credentials.
-
Copy connection details: Use the details provided in your 0DBC connection and paste them into DB Ever to complete the configuration.
How to manage databases from DB Ever?
Once the connection is complete, you can manage your databases and perform SQL queries in the most convenient way. You can create and delete tables, insert data, and perform queries:
CREATE TABLE student ( id INT, name VARCHAR(30), country_id INT);
INSERT INTO (id, name, country_id) VALUES(1, 'David', 1),(2, 'Rocío', 1),(3, 'Carlos', 2);
SELECT * FROM student;
In addition, you can do more complex queries such as joins to get related information:
SELECT e.id, e.name, p.name AS countryFROM student eINNER JOIN country p ON e.country_id = p.id;
SELECT e.id, e.name, p.name AS countryFROM student eLEFT JOIN country p ON e.country_id = p.id;
What advantages does Revpsheet offer over using pure SQL?
One of the biggest benefits of using Revpsheet is that you don't need to learn a new language or syntax; you can simply apply the traditional SQL you know, such as that used in PostgreSQL, Oracle or MySQL.
By connecting an external SQL client like DB Ever to Revpsheet, you can perform a wide range of operations on your data, from simple queries to complex database management, all while leveraging the power of Amazon AWS cloud computing - it's an important step towards modern data management!
With this knowledge and tools, we invite you to go ahead and explore all the possibilities Revpsheet offers you to improve your database management skills.
